This book was released on 2001 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le travail de thèse porte sur l'intégration d'algorithmes de commande des machines électriques à courant alternatif. Deux types de commande : une de type scalaire et une de type vectoriel ont été particulièrement étudiés et implantés avec deux stratégies différentes. D'abord, une commande vectorielle a été complètement câblée dans un circuit ASIC, puis une implantation mixte employant un circuit ASIC d'un côté et un processeur numérique (un DSP) de l'autre a été réalisée. Les architectures à structure modulaire qui ont été mis en œuvre comportent deo; unités fonctionnelles réutilisables. La mise en place de ces architectures a été rendue possible à l'aide de l'emploi d'une méthodologie de conception dite mixte. Une interface de simulation numérique/analogique de l'ensemble du système de commande et de la chaîne d'entraînement a, par ailleurs. été mise en place et testée sous l'environnement SPW. Enfin, pour introduire l'intégration du système de commande ainsi réalisée à l'aspect système proprement dit où la puissance doit cohabiter avec les circuits de contrôle, une ouverture vers cet approche environnementale a été développée à travers des mesure CEM.

Book excerpt: L’intégration des systèmes de commande électriques n'a été l'objet que de travaux marginaux dont aucun n'a envisagé jusqu'à présent une approche systématique du problème. Actuellement, l'intégration de la commande fait appel la plupart du temps à un processeur spécialisé type micro conducteur ou DSP couplé parfois à un ASlC, dédié à la génération des impulsions MLI de commande de l'onduleur. Cette approche de conception est peu réactive face aux changements de spécification et ne permet pas de traiter certains problèmes que nous identifions dans cette thèse (vérification des modèles, exploration de l'espace des solutions, etc...). Pour résoudre ces problèmes, nous proposons d’utiliser une méthodologie de conception mixte matériel/logiciel qui consiste à développer ensemble le la partie matériel (ASIC) et la partie logiciel (processeur) du système intégré à partir d'un modèle de spécification commun. Comme notre approche se limite aux systèmes de commande, nous avons adapté certaines tâches de .conception pour traiter des problèmes spécifiques tell que la preuve formelle des propriétés mathématiques du système. A partir de cette méthode, nous pouvons alors flot de conception utilisant différents langages (VHDL, Grafcet, Script MA TLAB) et outils correspondants. Dans le cas du Grafcet, nous montrons qu'en modifiant ses règles de fonctionnement en se basant sur l'hypothèse de syncl1ronisme fort. il devient possible de modéliser les fonctionnel. En se basant sur un ensemble de règles et de techniques que nous définissons, on peut alors analyser les modèles Grafcet en vue de l'intégration. Pour montrer la validité de la démarche adoptée. Nous avons intégré, sous forme d'ASIC, un algorithme de contrôle vectoriel de moteur asynchrone. Au niveau de chaque étape de conception, les solutions aux différents problèmes sont exposées En particulier, nous proposons d’utiliser l’algorithme CORDIC pour calculer le plupart des fonctions mathématiques (p.e. les rotations). Finalement. I'ASIC a été prototypé avec un FPGA et connecté au banc d’essai (onduleur, moteur et charge). Grace aux mesures de courant, de tension et de couple, le système intégré a pu être validé.

This book was released on 1998 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive book on sensorless high performance a.c. drives. It is essential reading for anyone interestred in acquiring a solid background on sensorless torque-controlled drives. It presents a detailed and unified treatment of sensorless vector-controlled and direct-torque controlled drive systems. It also discusses the applications of artificial intelligence to drives. Where possible, space vector theory is used and emphasis is laid on detailed mathematical and physical analysis. Sensorless drive schemes for different types of permanent magnet synchronous motors, synchronous reluctance motors, and induction motors are also presented. These include more than twenty vector drives e.g. five types of MRAS-based vector drives, and eleven types of direct-torque-controlled (DTC) drives, e.g. the ABB DTC drive. However, torque-controlled switched reluctance motor drives are also discussed due to their emerging importance. The book also covers various drive applications using artificial intelligence (fuzzy logic, neural networks, fuzzy-neural networks) and AI-based modelling of electrical machines. Finally, self-commissioning techniques are also discussed. This is a comprehensive thoroughly up-to-date, and self-contained book suitable for students at various levels, teachers, and industrial readership. Peter Vas is a Professor at the Department of Engineering at the University of Aberdeen, UK, where he is also the Head of the Intelligent Motion Control Group. His previous books published by Oxford University Press are extensively used worldwide.

Book Synopsis Cambridge Handbook of Engineering Education Research by : Aditya Johri
Download or read book Cambridge Handbook of Engineering Education Research written by Aditya Johri and published by Cambridge University Press. This book was released on 2014-02-10 with total page 1124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Book excerpt: This report reviews engineering's importance to human, economic, social and cultural development and in addressing the UN Millennium Development Goals. Engineering tends to be viewed as a national issue, but engineering knowledge, companies, conferences and journals, all demonstrate that it is as international as science. The report reviews the role of engineering in development, and covers issues including poverty reduction, sustainable development, climate change mitigation and adaptation. It presents the various fields of engineering around the world and is intended to identify issues and challenges facing engineering, promote better understanding of engineering and its role, and highlight ways of making engineering more attractive to young people, especially women.--Publisher's description.
