Using Combined Integration Algorithms for Real-time Simulation of Continuous Systems

Harbor, Larry Keith 01 January 1988 (has links) (PDF)
At many American colleges and universities, efforts to enhance the retention of a diverse group of students have become a priority. This study represents part of this effort at the University of Central Florida, a large public suburban state university in the South. Specifically, this investigation evaluated Pegasus '95 and the Academic Mentoring Program offered in the Summer and Fall Semesters of 1995 to specially-admitted students who fell short of regular admissions requirements. During the summer, Pegasus '95 provided testing, orientation, guided course work, study skills workshops, and mentoring, both individually and in the context of cohesive socialization groups of approximately 15 students each. In the Fall 1995 Semester, students were highly encouraged to participate in one-on-one mentoring in the Academic Mentoring Program (AMP) available through the Student Academic Resource Center (SARC), a university-based office which provides a variety of academic assistance services. A multiple regression analysis was conducted using the following independent predictor variables: gender, SAT/ACT scores, Pegasus participation, use of the AMP in the Fall 1995 semester, four summary scores from the College Student Inventory (CSI), and eight scaled scores from the Noncognitive Questionnaire (NCQ). Dependent variables were individual student GPA in the Summer and Fall 1995 semesters, cumulative GPA after two semesters, and enrolled credit hours into the Spring 1996 academic term. Overall, it was expected that a combination of predictor variables, including both traditional cognitive factors (SAT/ACT scores and high school GPA) and noncognitive factors (NCQ scores and CSI scores, Pegasus participation, and mentoring by the SARC) would significantly predict GP A and retention. The study found that a regression equation including gender, high school GPA, overall SAT scores and the eight NCQ scale scores significantly predicted Fall 1995 and cumulative GPA after two semesters but not Summer 1995 GPA or credit hours enrolled in Spring 1996. Attendance at Pegasus meetings was also shown to be significantly and positively associated with Fall 1995 GPA and cumulative GPA after two semesters but not of Summer 1995 GPA or credit hours enrolled in Spring 1996. Gender, high school GP A, the ACT score and the CSI Dropout Proneness scale significantly predicted credit hours enrolled in Spring 1996, as did use of the AMP program provided by the SARC. Of particular interest was the finding that including noncognitive factors in significant equations led to a greater explanation of the variance than could be obtained with any of the traditional cognitive measurements alone, suggesting that with academically disadvantaged students noncognitive measures must be considered in predicting who can succeed and persist in college.

No. of bitstreams: 1 Ludmila de Castro Piassi.pdf: 1615984 bytes, checksum: 902ec59c5c8cbea8c2e059d17aa83b9f (MD5) Previous issue date: 2011-10-04 / Este trabalho teve como objetivos: empregar o método de regulação da produção pelo controle por área com intuito de mensurar a capacidade de produção anual da floresta manejada; e testar a influência de métodos de regulação florestal no planejamento da produção de madeira. Esse problema foi proposto com o cuidado de que o mesmo apresentasse características semelhantes aos encontrados habitualmente nas empresas florestais. Para caracterização da área de estudo foram escolhidos, arbitrariamente, três capacidades produtivas (os índices de sítio I, II e III), plantios do híbrido Eucalyptus urograndis, idades dos plantios variando de 0 a 7 anos e 109 talhões. As variáveis coletadas foram as inerentes ao processo de produção, como preços de insumos, mão-de-obra e de madeira para celulose. Com base nesses dados, foi obtida a rotação econômica para cada capacidade produtiva utilizando o Benefício Periódico Equivalente como critério de avaliação econômica. Os modelos de otimização foram formulados pelo Modelo I, empregando-se o software SAD Florestal, que permitiu gerar as prescrições de manejo, bem como construir o modelo de otimização proposto. Ao final, avaliou-se cinco métodos de regulação: Método do controle por área, Método do controle por área considerando rotações menores, Modelo de programação linear, Modelo de programação linear inteira e modelo de programação linear inteira mista. O método de controle por área foi eficiente na orientação da determinação dos limites da restrição de imposição de produções anuais dos modelos de otimização. O método de controle por área apresentou a maior oscilação tanto na produção quanto na área de corte anual. Os métodos de otimização foram os que apresentaram menor coeficiente de variação para a produção anual de madeira. O maior lucro foi obtido pelo método de controle por área considerando rotações menores, devendo ser visto com ressalvas na medida em que a madeira obtida com quatro anos pode não ter o mesmo valor para aquela obtida com maior idade. O modelo de programação linear apresentou maior retorno líquido do que o método de programação linear inteira, sendo que este fato pode estar relacionado a restrição de regulação. No modelo de programação linear inteira mista as subdivisões nas áreas de corte dos talhões que permitiram essa opção, mostraram-se desproporcionais / This study aimed to: employ the method of production regulationusing controlper area with the purpose of measuring the annual production capacity of the managed forest; and test the influenceof forest regulation methodsin the planning of wood production.This problem was proposed in a way that it exhibits characteristics similar to those normally found in forestry companies.To characterize the study area,three productive capacities were chosen arbitrarily (siterates I, II and III), plantationsof the Eucalyptusurograndis hybrid, plantation agesvarying from 0 to 7 years and 109 plots.The variables collected were the ones inherent to the productionprocess, such as prices of input, manpower and wood for cellulose. Based on these data, it was obtained the economic rotation for each productive capacity using the Equivalent Periodic Benefit as a criterion for economic evaluation. The optimization models were formulated by Model I, using the SAD Forest software, which allowed generating management prescriptions, as well as creating the optimization model proposed. In the end, five regulatory methodswere evaluated: Method of control per area, Method of control perareaconsidering smaller rotations,Model of linear programming, Modelof integer linear programming and Model of mixed integer linear programming.The method of controlper area was effective in the orientation of determining the restriction limits of imposition of annual productions of the optimization models. The method ofcontrol per area showed the greatest fluctuation in the production and in the annual cutarea.The optimization methods presented the lowest coefficient of variation for the annual wood production. The higher profit was obtained by the method of control per area considering smaller rotations, and it should be viewed with caution, as the obtainedfour years old wood may not have the same value of the one obtained with higher age.The linear programming model had a higher net return than the integer linear programming method, and this fact may be related to regulation restrictions. In the model of mixed integer linear programming, the subdivisions in cutting areas of the plots that allowed this option were disproportionate

Low cost integration of Electric Power-Assisted Steering (EPAS) with Enhanced Stability Program (ESP)

Soltani, Amirmasoud January 2014 (has links)
Vehicle Dynamics Control (VDC) systems (also known as Active Chassis systems) are mechatronic systems developed for improving vehicle comfort, handling and/or stability. Traditionally, most of these systems have been individually developed and manufactured by various suppliers and utilised by automotive manufacturers. These decentralised control systems usually improve one aspect of vehicle performance and in some cases even worsen some other features of the vehicle. Although the benefit of the stand-alone VDC systems has been proven, however, by increasing the number of the active systems in vehicles, the importance of controlling them in a coordinated and integrated manner to reduce the system complexity, eliminate the possible conflicts as well as expand the system operational envelope, has become predominant. The subject of Integrated Vehicle Dynamics Control (IVDC) for improving the overall vehicle performance in the existence of several VDC active systems has recently become the topic of many research and development activities in both academia and industries Several approaches have been proposed for integration of vehicle control systems, which range from the simple and obvious solution of networking the sensors, actuators and processors signals through different protocols like CAN or FlexRay, to some sort of complicated multi-layered, multi-variable control architectures. In fact, development of an integrated control system is a challenging multidisciplinary task and should be able to reduce the complexity, increase the flexibility and improve the overall performance of the vehicle. The aim of this thesis is to develop a low-cost control scheme for integration of Electric Power-Assisted Steering (EPAS) system with Enhanced Stability Program (ESP) system to improve driver comfort as well as vehicle safety. In this dissertation, a systematic approach toward a modular, flexible and reconfigurable control architecture for integrated vehicle dynamics control systems is proposed which can be implemented in real time environment with low computational cost. The proposed control architecture, so named “Integrated Vehicle Control System (IVCS)”, is customised for integration of EPAS and ESP control systems. IVCS architecture consists of three cascade control loops, including high-level vehicle control, low-level (steering torque and brake slip) control and smart actuator (EPAS and EHB) control systems. The controllers are designed based on Youla parameterisation (closed-loop shaping) method. A fast, adaptive and reconfigurable control allocation scheme is proposed to coordinate the control of EPAS and ESP systems. An integrated ESP & ESP HiL/RCP system including the real EPAS and Electro Hydraulic Brake (EHB) smart actuators integrated with a virtual vehicle model (using CarMaker/HiL®) with driver in the loop capability is designed and utilised as a rapid control development platform to verify and validate the developed control systems in real time environment. Integrated Vehicle Dynamic Control is one of the most promising and challenging research and development topics. A general architecture and control logic of the IVDC system based on a modular and reconfigurable control allocation scheme for redundant systems is presented in this research. The proposed fault tolerant configuration is applicable for not only integrated control of EPAS and ESP system but also for integration of other types of the vehicle active systems which could be the subject of future works.
