Control of Non-conventional Synchronous Motors
Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors, synchronous and switched reluctance motors, stepping motors and piezoelectric motors. This book presents efficient controls to improve the use of these non-conventional motors. Contents 1.

Control of Synchronous Motors
Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.
Modélisation Et Commande de la MacHine Synchrone À Réluctance Variable
L'étude porte sur la modélisation et la commande d'une machine synchrone à réluctance variable présentant une cage au rotor. Nous avons développé un modèle saturé applicable à la simulation de l'ensemble convertisseur-machine (modification des équations de Park). Une part importante de notre travail a été consacrée à la réalisation de nombreux essais expérimentaux qui ont permis de valider les développements théoriques. Nous avons étudié le cas où la machine est reliée au réseau et le cas où la machine est pilotée en commande vectorielle. Pour la commande vectorielle, nous avons étudié les effets de la saturation sur la dynamique et sur le régime permanent pour une commande en couple et une commande en vitesse. Nous avons également développé et implanté une stratégie de commande permettant d'optimiser le rendement de la machine en mesurant la puissance absorbée et en utilisant un algorithme de recherche de minimum (Fibonacci, section dorée).
