Σκοπός της παρούσας διπλωματικής εργασίας είναι ο σχεδιασμός ενός ελεγκτή πέδησης για την ρυμουλκόμενη μονάδα μιας νταλίκας, ώστε αυτή να μην αποκλίνει της πορείας της κατά το φρενάρισμα. Αναλυτικότερα, στο κεφάλαιο 1 παρουσιάζεται η μορφή των τυπικών και πιο συνηθισμένων ρυμουλκόμενων οχημάτων (οδικά τρένα) και ορίζονται τα βασικά κομμάτια που το αποτελούν. Στο κεφάλαιο 2 παρουσιάζονται με χρήση κατάλληλων μαθηματικών και φυσικών προτύπων οι ταχύτητες και οι επιταχύνσεις καθώς και τα διάφορα συστήματα συντεταγμένων που απαιτούνται για την περιγραφή της κίνησης του οχήματος. Στο κεφάλαιο 3 αναλύεται το σύνθετο αλλά και το απλουστευμένο μοντέλο των οδικών τρένων, ενώ στο κεφάλαιο 4 αναλύουμε το δυναμικό μοντέλο του οχήματος tractorsemitrailer που αποτελεί και το αντικείμενο έρευνας της εργασίας. Υπολογίζουμε πλήρως τις εξισώσεις που περιγράφουν το σύστημα, με βάση κάποιες προϋποθέσεις όπως ότι κινείται στην ευθεία, με σταθερή διαμήκη ταχύτητα ενώ επίσης δεχόμαστε και το γραμμικό μοντέλο για τα ελαστικά. Τέλος, στο κεφάλαιο 5 σχεδιάζουμε ένα PD ελεγκτή και βρίσκουμε τις βέλτιστες τιμές των παραμέτρων του ώστε το σύστημα μας να παρουσιάζει όσο το δυνατόν μικρότερα σφάλματα. / Aim of present diplomatic work is the planning of controller of braking for the followinf unit of lorry, in order that this does not deviate her course at the break. More analytically, in capital 1 is presented the form the formal and more usual road trains and is fixed the basic pieces where constituting. In capital 2 are presented with use suitable mathematic and natural models the speeds and the accelerations as well as the various systems of coordinates that are required for the description of movement of vehicle. In capital 3 is analyzed the complex but also simplified model of road trains, while in capital 4 we analyze the dynamic model of vehicle tractorsemitrailer that is the subject of this work. We calculate the equations that describe the system, with base certain conditions as that it is moved in the straight line, with constant speed while also we accepted the linear model for the tyres. Finally, in capital 5 we draw a PD controller and we find the most optimal prices of parameters in order that our system presents as much as possible smaller faults.

Um SIG é destinado ao armazenamento, análise e exibição tanto de dados espaciais quanto dados não espaciais. Conseqüentemente, a fim de que um SIG possa funcionar de forma eficiente, são necessárias ferramentas que forneçam dinamismo na aquisição da informação, quando de sua construção ou atualização. A Fotogrametria Digital está entre as possíveis fontes de informação espacial. A fim de aumentar a densidade e velocidade na aquisição de tais informações, um maior grau de automatização das técnicas fotogramétricas é buscado. Seguindo esta tendência, este trabalho apresenta uma metodologia de complementação automática da malha viária rural. Esta metodologia divide-se em três passos básicos: 1) ordenação dos segmentos desconexos e desordenados de rodovia que compõem cada rodovia presente na imagem, via otimização em grafos; estes segmentos são previamente extraídos por uma metodologia de extração automática de segmentos de rodovia; 2) reconstrução das falhas de extração inerentes a cada rodovia, constituída no passo 1; e 3) reconhecimento e delineamento dos cruzamentos de rodovias. Na primeira etapa, os segmentos de rodovia são ordenados em ordem decrescente de comprimento e os pontos extremos de seus eixos médios são utilizados na construção de um grafo completo, no qual os nós e arestas são, respectivamente, os pontos extremos e as possíveis ligações entre eles. A partir deste grafo inicial estruturas chamadas árvores de permutações são geradas, possuindo como raízes os pontos extremos do atual segmento de rodovia mais longo (base). A busca ocorre à esquerda e à direita do atual segmento mais longo. / Nowadays, GIS (Geographical Information systems) is one of the most important information technologies. GIS is designed to store, analyze, and display spatial data as well non-spatial data. Consequently, in order to have a GIS working properly, it is necessary powerful tools for GIS data acquisition and updating. Digital Photogrammetry is one of the most important fields in spatial information data capture. In order to increase the density and the speed of spatial information capture processes, it is necessary to developed new photogrammetric tools with higher automation level. Following this tendency, this work proposes an automatic completion methodology of rural road networks. This methodology is subdivided into three basic steps: 1) ordering of disconnected and disordered road segments that belong to each road in the image by graph optimization; the road segments are previously extracted by a preexisting methodology for automatic road segment extraction; 2) reconstruction of the extraction gaps identified by the step 1; and 3) recognizing and delineation of the road crossings. In the first step, the road segments are ordered in decreasing order of length and the road segment centerline endpoints are used to construct a complete graph, where their nodes and edges are endpoints and relations between them, respectively. This graph are used to derive structures called permutation trees, having as roots the endpoints of the current longest road centerline segment (base). The searching is accomplished on the left and right sides of the current longest road segment. During the search procedure, two heuristics are used: the searching direction and the collinearity constraints. The tree edges that satisfy both heuristics are weighed by a weighing function that embodies geometric, radiometric, and topological road properties.
