Control of Non-conventional Synchronous Motors

Introduction ¹

For the countless operations of its machine tools, its robots and its “special machines”, modern industrial production is in dire need of electrical motors that can be used as “actuators”: these machines must impose a torque, speed or position on objects in movement (most often in rotation), all of which are determined by a high level decisional element. Execution speed and accuracy are necessary for high-quality productivity. Electrical motors have thus taken a dominant place in the “axis control” that we find everywhere in modern industrial production. We also find such motors in several “consumer product” applications, even if we will consider mainly professional applications in this book. Electrical motors are also present in the motorization of several modes of transport: terrestrial vehicles, free or guided, and ships. The present work specifically covers the “non-conventional” controls of synchronous actuators, and the control of “non-conventional” synchronous motors.

This book is part of a series published by ISTE-Wiley and Hermes-Lavoisier. The first book, devoted to the Control of Synchronous Motors [LOU 11], which studies “conventional” synchronous motors, has already been published in English. Let us add that another volume has been devoted to the identification and to the observation of electrical machines [FOR 10]. A further volume has presented general methods regarding the control of electrical machines [HUS 09], and still another has focused on ...
