This book was released on 2015-02-05 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: La commande vectorielle de la machine synchrone a aimants permanents necessite une connaissance precise de la position rotorique. Traditionnellement, cette position est obtenue a partir de l'utilisation d'un capteur mecanique. Depuis des annees, l'attention de la communaute scientifique s'est portee sur la limitation du nombre de capteurs vu que leur presence, non seulement augmente le cout et la complexite materielle totale, mais aussi reduit sa fiabilite avec une sensibilite additionnelle aux perturbations exterieures. Dans une premiere partie, nous proposons le capteur le mieux adapte pour une application automobile. Ce capteur est base sur le couplage intelligent entre un observateur et un capteur logiciel base sur la technique d'injection de signaux. Dans une deuxieme partie, nous proposons une methode simple et rapide permettant l'estimation de la resistance et des inductances statoriques a l'arret. La combinaison de l'identification a l'arret et du capteur logiciel permet une bonne estimation de la position de la machine synchrone a aimants permanents sur une large plage de vitesse y compris les basses vitesses et a l'arret.

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 240 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.

Download or read book Advanced Direct Thrust Force Control of Linear Permanent Magnet Synchronous Motor written by Muhammad Ali Masood Cheema and published by Springer. This book was released on 2021-02-13 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the direct thrust force control (DTFC) of tubular surface-mount linear permanent magnet synchronous motors (linear PMSMs). It presents a detailed account and analysis of several advanced nonlinear control schemes, based on the direct thrust control principle, to achieve a reduction in steady-state ripple in thrust force with faster transient response, and describes their experimental validation. It also provides rigorous details of the dynamic modelling of linear PMSMs from a control system perspective, and demonstrates the superior control performance of the proposed techniques compared to the current state-of-the-art techniques. Lastly, the book proposes and validates a stator flux observer for sensorless speed estimation comprising a linear state observer and an improved sliding mode component.
