Book Etude et Optimisation d une Machine Synchrone    Double Excitation

Download or read book Etude et Optimisation d une Machine Synchrone Double Excitation written by Daanoune Abdeljalil and published by Presses Academiques Francophones. This book was released on 2013-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans un contexte ou la question de la preservation de l'environnement est devenue un sujet societal majeur, la recherche de nouvelles technologies pour remplacer la voiture a essence constitue un veritable enjeu industriel. Les vehicules hybrides et electriques sont une alternative prometteuse aux vehicules conventionnels. Ce travail porte sur la conception et l'optimisation des machines electriques pour la motorisation de ces voitures. Au cours de ces travaux, nous avons developpe une nouvelle methodologie de dimensionnement et d'optimisation des machines synchrones a double excitation. L'interet de cette methode est son bon compromis entre la precision et le temps de calcul et sa capacite d'adaptation a plusieurs types de machines. Le second volet de ce livre est consacre a la proposition d'une nouvelle structure de machine synchrone a rotor bobine. Une technique originale de compensation de la reaction magnetique d'induit est mise en place, elle consiste en l'insertion d'aimants secondaires permettant de creer un flux dans l'axe q de la machine. Ce dernier a pour role d'affaiblir le flux de la reaction magnetique d'induit.

Book Permanent Magnet Synchronous Machines and Drives

Download or read book Permanent Magnet Synchronous Machines and Drives written by Wei Xu and published by CRC Press. This book was released on 2023-07-31 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permanent magnet synchronous motors (PMSMs) are popular in the electric vehicle industry due to their high-power density, large torque-to-inertia ratio, and high reliability. This book presents an improved field-oriented control (FOC) strategy for PMSMs that utilizes optimal proportional-integral (PI) parameters to achieve robust stability, faster dynamic response, and higher efficiency in the flux-weakening region. The book covers the combined design of a PI current regulator and varying switching frequency pulse-width modulation (PWM), along with an improved linear model predictive control (MPC) strategy. Researchers and graduate students in electrical engineering, systems and control, and electric vehicles will find this book useful. Features: • Implements evolutionary optimization algorithms to improve PMSM performance. • Provides coverage of PMSM control design in the flux-weakening region. • Proposes a modern method of model predictive control to improve the dynamic performance of interior PMSM. • Studies the dynamic performance of two kinds of PMSMs: surface-mounted and interior permanent magnet types. • Includes several case studies and illustrative examples with MATLAB®. This book is aimed at researchers, graduate students, and libraries in electrical engineering with specialization in systems and control and electric vehicles.

Book La commande   lectronique des machines

Download or read book La commande lectronique des machines written by Michel Pinard and published by Dunod. This book was released on 2013-08-28 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage permet de maîtriser les bases du contrôle et de la commande des machines électriques. Il est constitué d'une soixantaine de fiches pratiques rassemblées dans huit dossiers thématiques. Ces dossiers abordent successivement les questions des alimentations électriques, des convertisseurs de puissance, des différents types de machines (synchrones ou asynchrones), et des différents modes de commande et d'asservissement. Chaque fiche pose un problème précis et ponctuel et en explique la solution. Dans de nombreux cas, des simulations sur les logiciels tels que PSIM, VisSIM et LabVIEW permettent une approche concrète et opérationnelle des difficultés rencontrées dans la mise au point d'un système de commande.
