[pt] FORMAS DO INFAMILIAR: CONFIGURAÇÕES DO SIMULACRO NO TEMPO / [en] FORMS OF THE UNCANNY: CONFIGURATIONS OF THE SIMULACRUM IN TIMEIRENE DANOWSKI VIVEIROS DE CASTRO 11 January 2021 (has links)
[pt] Esta dissertação propõe uma análise do conceito de infamiliar (unheimlich)
com o objetivo de encontrar suas condições de possibilidade em determinados tipos
de discursos, nos quais esse sentimento ao mesmo tempo produz e é produzido por
uma forma de tempo própria. Diz-se infamiliar aquele sentimento que emerge tanto
no cotidiano como no contato com certas obras de ficção, como nota Freud em seu
ensaio de mesmo nome (das Unheimliche), deslanchado por uma pequena distorção
ou variação do familiar (isto é, daquilo que já é conhecido). O infamiliar diverge
profundamente do familiar, ainda que mantendo com este último uma semelhança
superficial, de aparência. Esta é sua principal característica, a saber, seu caráter de
simulacro, de falsa cópia do familiar. Interessamo-nos, portanto, por entender
melhor o tipo de discurso que se estrutura com base em um ou mais simulacros,
notadamente o discurso sofista. O infamiliar também se caracteriza, na ficção, por
vir frequentemente acompanhado de contradições cronológicas e por sugerir,
portanto, uma distorção no tempo e no espaço das histórias. Veremos, enfim, como
o discurso que opera por simulacros constrói uma forma do tempo específica e
própria. Nosso objetivo é borrar os limites do que denominamos infamiliar,
mostrando que ele nasce de particularidades da própria linguagem que estão
presentes em todo tipo de discurso, que ele não nos é tão estrangeiro assim e nem
tão particular a um grupo específico de gêneros literários. / [en] This dissertation proposes an analysis of the concept of uncanny (from the
German unheimlich; or infamiliar, the negation of familiarity) with a focus on
finding its conditions of possibility in certain types of discourses in which this
feeling both produces and is produced by a distinct form of time. The infamiliar is
said to be a feeling which emerges both in daily life and in contact with certain
works of fiction (as Freud notes in his essay of the same name, das Unheimliche),
produced by a small distortion or variation of the familiar (that is, of that which is
already known). It differs profoundly from the familiar all the while maintaining
with the latter a superficial resemblance, that is, a similarity in appearance. This is
its main characteristic, namely, being a simulacrum, or false copy, of the familiar.
What follows is a deeper analysis of the types of discourse that are structured around
simulacra, notably the sophist discourse. The uncanny is also characterized, in
fiction, by often accompanying chronological contradictions which suggest a
distortion of space and time in such stories. Therefore, we will also see how the
type of discourse that operates through simulacra constructs a distinct form of time.
Our goal is to blur the limits of the uncanny, showing that it is a product of certain
particularities of language that are present in all types of discourses and so that it is
neither very foreign to us nor restricted to a specific group of literary genres.

[pt] O QUE A ESFINGE ENSINA A ÉDIPO: OS LIMITES DA INTERPRETAÇÃO, O DEMONÍACO E O INFAMILIAR NA ARTE CONTEMPORÂNEA / [en] WHAT THE SPHINX TEACHES OEDIPUS: THE LIMITS TO INTERPRETATION, THE DEMONIC AND THE UNFAMILIAR IN CONTEMPORARY ARTJULIANA DE MORAES MONTEIRO 17 February 2020 (has links)
[pt] A presente tese investiga o que o filósofo italiano Giorgio Agamben chamou de a semiologia do ponto de vista da Esfinge em seu livro Estâncias: a palavra e o fantasma na cultura ocidental. No capítulo A imagem perversa: a semiologia do ponto de vista da Esfinge, o filósofo propunha um modelo de significação calcado não no significado, mas na barreira resistente à significação que, para ele, seria a marca indelével de uma objeção à imposição do sentido. Para ele, Édipo seria o paradigma da cultura ocidental na qual o que ele chama de metafísica do significado foi forjada, na medida em que o personagem trágico resolve o enigma da Esfinge. Assim, Agamben repensa o estatuto da linguagem enquanto adequação do significante ao significado para construir uma perspectiva calcada na dissonância implicada no signo e na assunção do enigmático enquanto modo de operar da linguagem. Tendo em vista a afirmação de Agamben de que na estética essa formulação do desacordo do signo aparece como exemplar, desenvolvo nesta pesquisa um estudo sobre a semiologia do ponto de vista da Esfinge e sua relação com a arte contemporânea. Para realizar esse objetivo, no primeiro capítulo faço um diagnóstico do modo como o pensamento sobre a linguagem se torna preponderante para a arte do século XX a partir do linguistic turn e do advento da Linguística e da Psicanálise; no segundo capítulo, investigo o conceito de demoníaco, na medida em que Agamben afirma que o signo é formado pela distorção demoníaca do nexo que une cada significante ao próprio significado e, por fim, abordo o tema da infamiliariedade (estranhamento) na relação entre arte e linguagem, tendo como ponto de partida o ensaio Das Unheimliche, publicado por Freud em 1919, uma das referências para Agamben pensar sua noção de semiologia esfíngica. / [en] The present thesis investigates what the italian philosopher Giorgio Agamben called the semiology from the point of view of the Sphinx in his book Stanzas: word and phantasm in western culture. In the chapter The perverse image: the semiology from the Sphyns s point of view , the philosopher was proposing a signification model that was not grounded on the signified, but on the barrier resisting signification that, for him, was the indelible mark of an objection to the imposition of meaning. For him, Oedipus would be the paradigm of the western culture, in which it was forged what Agamben called the metaphysics of the signified, given that the tragic protagonist solves the Sphinx s enigma. Therefore, Agamben rethinks the status of language as the adequacy of the signifier to the signified to build a perspective centered on the dissonance implied in the sign and on the assumption of the enigmatic as a means of language operation. In view of Agamben s affirmation, that in aesthetics this formulation of the sign s discord exemplarily appears, I develop in this research a study on the semiology from the point of view of the Sphinx and its relations with contemporary art. To accomplish this goal, in the first chapter I make a diagnosis on the way that the thinking on language becomes preponderant to twentieth century art since the linguistic turn and the advent of Linguistics and Psychoanalysis; in the second chapter, I investigate the concept of demonic, according to Agamben s affirmation that the sign is formed by the demonic distortion of the bond that unites each signifier to its own signified and, lastly, I approach the theme of unfamiliarity (uncanny) in the relationship between art and language, with the starting point being the essay Das Umheimliche, published by Freud in 1919, one of the influences to Agamben for thinking on his notion of Sphinx s semiology.

Navigationskonceptet DSI:s påverkan på användarupplevelsen : En studie av en elektronisk turistbroschyr / The navigation concept DSI's impact on the user experience : A study of an electronic tourist brochureRaattamaa, Lena, Ghazali, Mirna January 2015 (has links)
En turistbroschyr är en bekant produkt som turister kan hämta information ifrån. Men hur upplever användarna interaktionen med ett obekant navigationskoncept som vi kallar DSI i kontexten av att söka turistinformation och vad har DSI för påverkan på användarupplevelsen? Vi har utfört en studie på tio respondenter. Studien inkluderar en observation där respondenterna har fått interagera, med applikationen vi skapade med navigationskonceptet DSI, och utföra ett antal uppgifter. De har även fått utföra ett antal uppgifter på en PDF med samma innehåll men med en annan struktur. Därefter utförde vi metoden Product Reaction Cards och till sist en intervju. Vi kom fram till att det tar tid att lära sig någonting obekant som DSI men när respondenterna väl har lärt sig konceptet så har det haft en positiv påverkan på användarupplevelsen och majoritet ansåg den som användbar i kontexten av att söka turistinformation. / A tourist brochure is a familiar product that tourists collect information from. But how do users experience the interaction with an unfamiliar navigation concept we call DSI in the context of seeking tourist information and what impact does DSI have on the user experience (UX)? We conducted a study of ten respondents. The study includes an observation in which the respondents had to interact with the application we created with the navigation concept DSI, and perform a number of tasks. They also performed a number of tasks on a PDF with the same content but with a different structure. Afterwards we performed the method Product Reaction Cards and lastly an interview. We concluded that it takes time to learn something unfamiliar as DSI but when the respondents have learned the concept it turned out to have a positive impact on the user experience and the majority considered it useful in the context of seeking tourist information.

漢賦語法風格研究 / The Study On the Grammar Style of Han Rhapsody(Fu)丁憶如, Ding, Yi Ru Unknown Date (has links)
辭賦在兩漢四百多年間,由於作者身分逐漸轉換,傳播方式的改易,還有文人對五七言句的接受,及政治環境的崩解等因素,導致其語言形式產生明顯變化,有漸趨駢偶、篇幅縮減等傾向。為了說明其語言風格與時俱「變」的軌跡,本文以169篇現存完整的漢賦為觀察對象,具體地描述並比較兩漢賦的種種異同,也嘗試將原本以作者等單「點」研究為主的語言風格學,延伸為一斷代賦史的「線」性觀察,更全面地回應賦學和文學史的研究成果。
本文第一章交代研究動機、方法及範圍,第二章則針對漢賦排比成篇的特徵,討論其句式風格及與五七言詩的關係;第三章進一步分析排比句中的「假平行」現象,並指出其與近體詩「假平行」不同的對仗習慣。第四章從較為宏觀的「篇章架構」著手,一方面呈現西漢著重時空順序的特徵,另方面也說明東漢建安小賦以首句概括全篇的安排。在第五章,筆者敘述漢賦「鋪彩摛文」的設計,包括使用長主語、長賓語以炫耀博學,竭力排比長謂語的種種動態,乃至多採「奔行」等手法;第六章則援引俄國形式主義學者所謂的「陌生化」概念,說明漢賦穿插「零句」和倒置語序,以引起聽眾或讀者新鮮感的安排。最後,第七章結論略述各章梗概,說明本文價值、研究限制和可繼續發展的相關議題。此外,〈附錄一〉〈附錄二〉是第二章的補充資料,分別為各篇句式分析表,以及二三、四三節奏賦句列表。 / Researchers of Han Rhapsody often suggest that, as a dominant literary genre of the Han Dynasty, rhapsody had changed its linguistic style gradually owing to the differences from the changes of authors’ social identities, the growing popularity and development of five and seven syllables(五七言詩), and the decline and fall of the Han empire. However, research that describes the specific and concrete features of this genre during the four hundred years of Han Dynasty is scant.
To illustrate how the varying line length, loose parallelism, and extensive themes in Han Rhapsody was built up, interacted with the five and seven syllables(the representative genre of the six dynasty(魏晉六朝)), and influenced other rhythm works for the following millennium, I described, grouped, and integrated all the distinguishing details in Han Rhapsodies with the method which Leo Spitzer had mentioned in his work, Linguistics and Literary History: Essays in Stylistics.
By analyzing the syntactic mode(句式), the pseudo parallel(假平行),the discourse- oriented topics, and the strategies the authors took to extend the length of the rhapsody and to unfamiliarize the readers with the incomplete or inverted sentence, this study showed how the complicated expressions, exhaustive details, and magnificent structures had been simplified and shortened, and both the authors and readers paid more attention to the emotions expressed rather than to the exaggerated language adapted step by step. To conclude, this study may be of importance in providing researchers with a better understanding of how the changes within a genre had taken place, as well as enriching the realm of the traditional Chinese literary criticism, which usually explains the literature phenomenon by subjective impression.

Navigating NPD in Unfamiliar Markets : Keys for a Successful Process Execution in Uncertainty / Navigera ny produktutveckling i okända marknader : Nycklar för ett framgångsrikt processutförande i en osäker miljöJonsson, Julia, Strand, Hildegunn January 2023 (has links)
Innovation is a crucial activity to ensure companies’ viability and is increasingly important to sustain competitive advantage. Globalization and the accelerating technological development are creating new markets previously not explored. Companies’ capability to execute New Product development (NPD) under these circumstances is limited since this is a new setting for most companies. Literature reveals that developing highly innovative products entails higher potential of economic growth and this incentivizes companies to explore opportunities in unfamiliar markets. It is also previously empirical shown that the NPD process for products targeting unfamiliar respectively familiar markets should differ due to their varying nature. Despite this, companies tend to use the same NPD processes regardless of the market situation which furthermore can hinder companies from succeeding with innovations targeting unfamiliar markets. Considering this, the purpose of this thesis is to explore and identify which aspects within the execution of the NPD process that enable respectively inhibit companies to achieve commercial success in markets of different characteristics. To investigate this, a multiple case study was conducted at a Swedish manufacturer of industrial machines. Two cases representing unfamiliar respectively familiar markets were studied through employee interviews, observations, reading internal documents and informal meetings. The study was conducted with an abductive approach, investigating the empirical reality and existing literature simultaneously. The result of this study reveals aspects that are challenging for companies to contemplate when executing NPD in unfamiliar markets and how it contrasts to the conditions for familiar markets. Raising companies’ awareness of this enables them to be better equipped for executing NPD under unfamiliar market conditions. The main challenges concluded are allocation of human resources and competency utilization, deficient collection of market and customer information, and insufficient communication routines. Moreover, companies fail to evaluate the potential and risk of innovations and have a hard time developing and implementing an NPD process that supports both structure and flexibility in markets with different characteristics. The biggest difference with NPD for unfamiliar market is the level of uncertainty. The challenge of understanding the customer needs and the competitors becomes more tangible for unfamiliar markets, and further places agreat demand on a working communication system, flexibility, cross-functionality, good risk assessment and well-defined product requirements. / Innovation är avgörande för att säkerställa företagens lönsamhet och blir allt viktigare för att upprätthålla konkurrenskraft. Globaliseringen och den accelererande tekniska utvecklingen skapar nya marknader som tidigare inte utforskats. Företagens förmåga att genomföra utveckling av nya produkter (NPD) under dessa omständigheter är begränsade eftersom detta är en ny miljö för de flesta företag. Litteratur visar att utveckling av mycket innovativa produkter skapar större potential för ekonomisk tillväxt och detta uppmuntrar företag att utforska möjligheter i okända marknader. Det är också tidigare empiriskt visat att NPD-processen för produkter som riktar sig mot okända respektive kända marknader bör skilja sig åt på grund av deras varierande karaktär. Trots detta tenderar företag att använda samma NPD-processer oavsett marknadssituation, vilket dessutom kan hindra företag från att lyckas med innovationer som riktar sig mot okända marknader. Med bakgrund i detta är syftet med detta examensarbete att utforska och identifiera vilka aspekter inom genomförandet av NPD-processen som gör det möjligt, respektive hämmar för företag att nå kommersiell framgång på marknader med olika karakteristik. För att undersöka detta genomfördesen fallstudie hos en svensk tillverkare av industrimaskiner. Två fall som representerade okänd respektive känd marknad studerades genom intervjuer, observationer, läsning av interna dokument och informella möten. Studien genomfördes med ett abduktivt tillvägagångssätt, som undersökte den empiriska verkligheten och befintlig litteratur samtidigt. Resultatet av denna studie identifierar aspekter som är utmanande för företag när de utför NPD i okända marknader och hur detta kontrasterar mot förhållandena i kända marknader. Genom att öka företags medvetenhet om detta kan de bli bättre rustade för att utföra NPD under olika marknadsförhållanden. De främsta utmaningarna som har identifierats är allokering av personalresurser och kompetensutnyttjande, bristfällig insamling av marknads- och kundinformation samt otillräckliga kommunikationsrutiner. Dessutom misslyckas ofta företag med att utvärdera innovationers potential och risk, och har svårt att utveckla och implementera en NPD-process som stödjer både struktur och flexibilitet i marknader med olika egenskaper. Den största skillnaden med NPD i okända marknader är nivån av osäkerhet. Utmaningen att förstå kundernas behov och konkurrenterna blir mer påtaglig i okända marknader och ställer vidare stora krav på ett fungerande kommunikationssystem, flexibilitet, tvärfunktionalitet, riskbedömning och väldefinierade produktkrav.

Comprendre la situation d’interaction entre des personnes vivant avec de l’aphasie et les interlocuteurs non-familiers de leur communautéAnglade, Carole 08 1900 (has links)
Contexte
L’aphasie, conséquence d’une lésion neurologique, est une difficulté à parler, comprendre, lire ou écrire. La diminution de qualité de vie des personnes vivant avec une aphasie (PVA) ne serait pas associée à la sévérité de l’aphasie, mais à leur participation - c’est à dire la façon dont une personne fonctionne dans la société. Les PVA réalisent moins d’activités sociales, et s’en montrent insatisfaites. Elles éprouvent de la difficulté à communiquer dans leurs échanges du quotidien, y compris avec des personnes non familières de la communauté comme les commis, serveurs, etc. Quand ces interactions sont jugées trop difficiles, les PVA peuvent en venir à éviter de communiquer avec d’autres interlocuteurs que leurs proches et s’enfermer dans un environnement de communication protégé mais limité. Ceci ne leur permet plus de s'engager dans la société autant qu’elles le souhaiteraient. En s’isolant ainsi, leur qualité de vie est menacée. Il est donc à la fois nécessaire et important de favoriser les interactions des PVA en dehors du domicile, ce qui est encore peu courant dans les interventions orthophoniques proposées en réadaptation. Pour cela, il faut pouvoir comprendre les situations dans lesquelles les PVA peuvent s'engager dans le cadre de leurs activités quotidiennes. Or peu d’écrits ont étudié en détail les situations d'interaction entre des PVA et les interlocuteurs non familiers de leur communauté.
Objectif
L’objectif de ce projet doctoral est de comprendre la situation d’interaction entre des PVA et des interlocuteurs non familiers de leur communauté.
Méthodologie
Trois études furent réalisées.
- Nous avons effectué une première étude à visée exploratoire avec l'objectif de décrire, grâce à l'analyse de conversation, la structure de ces interactions de service récoltées auprès de 6 PVA (étude 1).
- À partir de la première étude et toujours grâce à l'analyse de conversation, nous avons réalisé une nouvelle étude, visant à décrire comment ces 6 PVA faisaient comprendre leurs requêtes lors des interactions de service malgré leur aphasie (étude 2).
- Enfin, dans une troisième étude nous avons cherché à comprendre - avec une étude de cas - comment une personne dont l'aphasie était sévère vivait la situation d’interaction de service au quotidien (étude 3).
Résultats
Dans l'étude 1, nous avons décrit les situations d’interaction de service de la vie quotidienne (ISQ) pour les PVA, et en avons notamment relevé la structure en quatre étapes sur le plan de la communication. Les interlocuteurs doivent s’entendre sur :
1) leur disponibilité à réaliser l’interaction,
2) l’objet de l’achat,
3) son prix,
4) le fait que l’interaction commerciale est terminée.
Cette étude a également révélé que :
- Les étapes 1 et 4, au cours desquelles la PVA doit faire comprendre à l’interlocuteur qu’elle est prête à commencer / clore l’interaction, ne représentent pas de défi spécifique pour les PVA.
- Les étapes 2 et 3 peuvent pour leur part représenter des défis sur le plan de la communication. L'étape 2 visant à faire comprendre à l’interlocuteur l’objet de l’achat ou de l’intérêt de la PVA, l’interaction sera facilitée si la PVA peut se servir elle-même ou pointer sur des supports visuels. L'étape 3 sera facilitée si le montant est visible au moment où la PVA prend connaissance du prix qu'elle doit payer.
Cette première étude a ainsi permis de mieux circonscrire les sources de défis sur le plan de la communication pour les PVA lors d’interactions à la caisse.
Dans la deuxième étude, nous nous sommes spécifiquement penchées sur l'étape 2 des interactions de service afin d'analyser comment les PVA font comprendre l’objet de leur intérêt à leurs interlocuteurs. Nous avons examiné comment la PVA exprimait sa requête, et comment l’interlocuteur y réagissait. Cette étude mit en lumière la façon dont les personnes vivant avec une aphasie même sévère pouvaient faire comprendre l’objet de leur requête lors des interactions de service en appuyant leur communication non verbale dans le contexte et l’environnement physique de l’interaction.
Dans notre étude 3, nous avons montré que la participation aux interactions de service de la vie quotidienne (ISQ) semblait liée chez le participant de cette étude de cas à la confiance qu’il avait dans sa capacité à réaliser l’ISQ malgré son trouble du langage. Ce participant a démontré un éventail de savoir-être et savoir-faire lissant l’interaction là où l’aphasie aurait pu l’écorcher, lui permettant d'obtenir le bien ou le service qu'il désirait, tout en donnant l'image d'un bon client, et ce malgré son aphasie.
Conclusions
Les interactions de service représenteraient une situation de communication dans laquelle les PVA pourraient participer de façon autonome et efficace. Leur structure, contexte et environnement physique pourraient permettre d'appuyer la communication non-verbale des PVA, et la relation de service orienterait les interlocuteurs vers une collaboration dans l'échange. Il est possible pour les PVA - mêmes celles dont l'aphasie est sévère - d'avoir confiance dans leur communication dans les situations d’interactions de service avec des personnes non familières, et de participer dans leur communauté de façon plus satisfaisante. / Background
Aphasia is a difficulty in speaking, understanding, reading or writing as a result of neurological damage. The quality of life of people living with aphasia (PLWA) is not related to the severity of aphasia, but to their participation - that is, how well a person functions in society. PLWA perform fewer social activities and are less satisfied with them. They find it difficult to communicate in their daily interactions, including with people unfamiliar within their community such as clerks, waiters, etc. They have difficulty communicating in their daily interactions. If these interactions are felt to be too difficult, PLWA may avoid communicating with people other than their relatives, and remain in a protected but limited communication environment. This does not allow them to engage in society as much as they would like. By isolating themselves this way, their quality of life is threatened. It is therefore important to encourage PLWA’s interactions outside their home, which is still uncommon in speech-language pathology interventions offered in rehabilitation. This requires an understanding of the situations in which PLWA may engage in their daily activities. However, there is little literature that has examined in detail the situations in which PLWA interact with unfamiliar people in their community.
Objective
The objective of this Ph.D. project is to understand the situation of interaction between PLWA and unfamiliar people within their community.
Methodology
Three studies were carried out. The first is an exploratory study whose objective is to describe through conversation analysis the structure of service encounters collected from 6 PLWA (study 1). Based on Study 1 and still using conversation analysis, we conducted a new study to describe how these 6 PLWA made their requests understood during service interactions despite their aphasia (study 2). Finally, in a third study we sought to understand with a case study how a person with severe aphasia experienced this communication situation in everyday life (study 3). Results
In Study 1, we described the Daily Service Encounter (DSE) situations for PLWA, including the four-step communication structure. Interlocutors must agree on: 1) their availability to perform the interaction, 2) the purpose of the purchase, 3) the price, 4) that the business interaction is complete. This study also found that: -Steps 1 and 4, where the PLWA must make the interlocutor understand that they are ready to begin/end the interaction, do not present specific challenges for PLWA. -Steps 2 and 3 however may present communication challenges. Since Step 2 aims to make the clerk understand the purpose of the purchase, the interaction will be facilitated if PLWA can help themselves or point to visual aids. Step 3 will be facilitated if the price is visible when PLWA are ready to pay. This initial study thus made it possible to better identify the sources of communication challenges for PLWA at the checkout.
In the second study, we specifically looked at Step 2 of the service interactions in order to analyze how PLWA make the clerks understand the purpose of their interest. We looked at how the PLWA expressed their request, and how the clerks responded to it. This study highlighted how PLWA – even severe aphasia - could make the subject of their request understood during service encounters by supporting their non-verbal communication in the context and physical environment of the interaction.
In our third study, we found that participation in DSE appeared to be related - in this case study - to the confidence of the participant in his ability to perform the DSE despite his language impairment. This participant demonstrated a range of interpersonal skills and abilities that smoothed interaction where aphasia might have nicked it, enabling him to obtain the good or service he wanted, while still presenting the image of a good customer, despite his aphasia. Conclusion Service encounters provide communication situations in which PLWA could participate effectively. Their structure, context, and physical environment would support the non-verbal communication of PLWA, and the service relationship would direct the interlocutors towards collaborative exchange. It is possible for PLWA - even those with severe aphasia - to be confident in their communication with unfamiliar people in service encounters, and to participate in their community in a more satisfying manner.

REAL-TIME UPDATING AND NEAR-OPTIMAL ENERGY MANAGEMENT SYSTEM FOR MULTI-MODE ELECTRIFIED POWERTRAIN WITH REINFORCEMENT LEARNING CONTROLBiswas, Atriya January 2021 (has links)
Energy management systems (EMSs), implemented in the electronic control unit (ECU) of an actual vehicle with electri ed powertrain, is a much simpler version of the theoretically developed EMS. Such simpli cation is done to accommodate the EMS within the given memory constraint and computational capacity of the ECU. The simpli cation should ensure reasonable performance compared to theoretical EMS under real-life driving scenarios. The process of simpli cation must be effective to create a versatile and utilitarian EMS. The reinforcement learning-based controllers feature pro table characteristics in optimizing the performance of controllable physical systems as they do not mandatorily require a mathematical model of system dynamics (i.e. they are model-free). Quite naturally, it can aspired to testify such prowess of reinforcement learning-based controllers in achieving near-global optimal performance for energy management system (supervisory) of electri ed powertrains. Before deployment of any supervisory controller as a mainstream controller, they should be essentially scrutinized through various levels of virtual simulation platforms with an ascending order of physical system emulating-capability. The controller evolves from a mathematical concept to an utilitarian embedded system through a series of these levels where it undergoes gradual transformation to finally become apposite for a real physical system. Implementation of the control strategy in a Simulink-based forward simulation model could be the first stage of the aforementioned evolution process. This brief will delineate all the steps required for implementing an reinforcement learning-based supervisory controller in a forward simulation model of a hybrid electric vehicle. A novel framework of loss-minimization based instantaneous optimal strategy is introduced for the energy management system of a multi-mode hybrid electric powertrain in this brief. The loss-minimization strategy is flexible enough to be implemented in any architecture of electrified powertrains. It is mathematically proven that the overall system loss minimization is equivalent to the minimization of fuel consumption. An online simulation framework is developed in this article to evaluate the performance of a multi-mode electrified powertrain equipped with more than one power source. An electrically variable transmission with two planetary gear-set has been chosen as the centerpiece of the powertrain considering the versatility and future prospects of such transmissions. It is noteworthy to mention that a novel architecture topology selected for this dissertation is engendered through a series of rigorous screening process whose workflow is presented here with brevity.
One of the legitimate concern of multi-mode transmission is it's proclivity to contribute discontinuity of power-flow in the downstream of the powertrain. Mode-shift events can be predominantly held responsible for engendering such discontinuity. Advent of dynamic coordinated control as a technique for ameliorating such discontinuity has been substantiated by many scholars in literature. Hence, a system-level coordinated control is employed within the energy management system which governs the mode schedule of the multi-mode powertrain in real-time simulation. / Thesis / Doctor of Philosophy (PhD)
