Study and Implementation of Hysteresis Controlled Inverter on a Permanent Magnet Synchronous Machine

In order to set up brushless dc servomotors, a specially designed permanent magnet machine has been associated with a transistorized inverter. First, the different parts of the machine/inverter/control assembly are described. Then a numerical simulation of this assembly is presented. This simulation has been used to study different control strategies that have been implemented on the experimental device: the results obtained are presented and discussed.
