Ibilgailu elektrikoen propultsio-sistemen RT-LAB plataforma bidezko simulazio-prozesuaren automatizazioa

Laburpena: gradu amaierako proiektu honetan ibilgailu elektrikoen propultsio-sistemen RT-Lab plataforma bidezko simulazio-prozesuaren automatizazioa deskribatzen da. Proiektu hori burutzeko beharra gaur egungo egoera klimatikoaren ondorioz sortu da. Garraioa berotegiefektuaren iturri nagusienetako bat denez, ibilgailu elektrikoen garapena sustatzea behar bat moduan ikusten da, zero emisioko ibilgailuak direla eta. Hala ere, horiek ezarri baino lehen, beharrezkoak diren simulazioak egin behar dira. Jakinda propultsio-sistema ibilgailu elektrikoen osagai nagusia dela, propultsio-sistemetan oinarritutako simulazioak garatu behar dira horien diseinu-prozesuan zehar. Hori guztia kontuan izanik, lan-denbora aurrezteko simulazio horiek automatizatzea da aukerarik onena. Horretarako, OPAL-RTren OP4510 platarforma erabiliz, APERT ikerkuntza-taldearentzat baliagarria izango diren script desberdinak garatu dira. Alde batetik, simulazio azeleraturako automatizazio-script-a, eta bestetik, denbora errealeko simulaziorako automatizazio-script-a. Hori egindakoan, script-a inplementatu eta emaitzak aztertu dira.Resumen: en este trabajo de n de grado se describe el proceso automatizado de las simulaciones del sistema de propulsión de los vehículos eléctricos utilizando la plataforma RT-LAB. La necesidad de llevar a cabo este trabajo ha surgido a raíz de la situación climática actual. El transporte es una de las principales causas del efecto-invernadero, por lo tanto, se ha encontrado la necesidad de impulsar el desarrollo de los vehículos eléctricos, debido a que son vehículos que emiten 0 emisiones. Teniendo en cuenta que el sistema de propulsión es el elemento principal de los vehículos eléctricos, hay que desarrollar simulaciones en base a los sistemas de propulsión. Teniendo en cuenta todo lo citado anteriormente, para poder rebajar el tiempo de trabajo invertido en las simulaciones, automatizar esas simulaciones sería la mejor opci ón. Para ello, se han desarrollado diferentes scripts que serán útiles para el grupo de investigación APERT utilizando la plataforma OP4510 de OPAL-RT. Por un lado, se ha desarrollado el script que automatiza simulaciones en tiempo acelerado y, por otro lado, se ha desarrollado el script para automatizar simulaciones en tiempo real. A continuación, se han implementado los scripts y se han analizado los resultados.Abstract: in this end-of-degree project, the automation of electric vehicles' propulsion system is described, by means of RT- Lab platform simulation process. The need to carry out this project is based on today's climate situation. As transport is one of the main causes of the greenhouse e ect, promoting the use of electric vehicles is seen as a real necessity, since they are zero emission means of transport. However, before implementing them, some simulations must be done. Taking into account that the propulsion system is the main part of electric vehicles, simulations based on propulsion system must be developed. Bearing every aspect in mind and in order to save time, the best option is to automate those simulations. For this purpose, by using an OPAL-RT OP4510 platform, various scripts that will be useful for APERT research group have been developed. Firstly, the automation script for accelerated simulation, and secondly, the automation script for real time simulation. After carrying that out, the script has been implemented and the results have been examined

Actuators for Intelligent Electric Vehicles

This book details the advanced actuators for IEVs and the control algorithm design. In the actuator design, the configuration four-wheel independent drive/steering electric vehicles is reviewed. An in-wheel two-speed AMT with selectable one-way clutch is designed for IEV. Considering uncertainties, the optimization design for the planetary gear train of IEV is conducted. An electric power steering system is designed for IEV. In addition, advanced control algorithms are proposed in favour of active safety improvement. A supervision mechanism is applied to the segment drift control of autonomous driving. Double super-resolution network is used to design the intelligent driving algorithm. Torque distribution control technology and four-wheel steering technology are utilized for path tracking and adaptive cruise control. To advance the control accuracy, advanced estimation algorithms are studied in this book. The tyre-road peak friction coefficient under full slip rate range is identified based on the normalized tyre model. The pressure of the electro-hydraulic brake system is estimated based on signal fusion. Besides, a multi-semantic driver behaviour recognition model of autonomous vehicles is designed using confidence fusion mechanism. Moreover, a mono-vision based lateral localization system of low-cost autonomous vehicles is proposed with deep learning curb detection. To sum up, the discussed advanced actuators, control and estimation algorithms are beneficial to the active safety improvement of IEVs

Mobile Robots Navigation

Mobile robots navigation includes different interrelated activities: (i) perception, as obtaining and interpreting sensory information; (ii) exploration, as the strategy that guides the robot to select the next direction to go; (iii) mapping, involving the construction of a spatial representation by using the sensory information perceived; (iv) localization, as the strategy to estimate the robot position within the spatial map; (v) path planning, as the strategy to find a path towards a goal location being optimal or not; and (vi) path execution, where motor actions are determined and adapted to environmental changes. The book addresses those activities by integrating results from the research work of several authors all over the world. Research cases are documented in 32 chapters organized within 7 categories next described

1992 NASA/ASEE Summer Faculty Fellowship Program

For the 28th consecutive year, a NASA/ASEE Summer Faculty Fellowship Program was conducted at the Marshall Space Flight Center (MSFC). The program was conducted by the University of Alabama and MSFC during the period June 1, 1992 through August 7, 1992. Operated under the auspices of the American Society for Engineering Education, the MSFC program, was well as those at other centers, was sponsored by the Office of Educational Affairs, NASA Headquarters, Washington, DC. The basic objectives of the programs, which are the 29th year of operation nationally, are (1) to further the professional knowledge of qualified engineering and science faculty members; (2) to stimulate and exchange ideas between participants and NASA; (3) to enrich and refresh the research and teaching activities of the participants' institutions; and (4) to contribute to the research objectives of the NASA centers

Exploring the Unknown: Selected Documents in the History of the US Civilian Space Program

One of the most important developments of the twentieth century has been the movement of humanity into space with machines and people. The underpinnings of that movement -why it took the shape it did; which individuals and organizations were involved; what factors drove a particular choice of scientific objectives and technologies to be used; and the political, economic, managerial, and international contexts in which the events of the space age unfolded- are all important ingredients of this epoch transition from an earthbound to spacefaring people. This desire to understand the development of spaceflight in the United States sparked this documentary history series. 'Exploring the Unknown' is a multi-volume series containing a selection of key documents in history of the U.S. civil space program. This current volume, Volume III, focusing on the use of space for practical applications, prints 112 key documents on the history of satellite communications, remote sensing of earth, and space as an investment in economic growth, edited for ease of use. Each is introduced by a headnote providing context, bibliographical information, and background information necessary to understanding the document
