Abstract :
Presented in this paper is an extension to previous work on observer-based sensorless control of synchronous reluctance motors. The extensions include a systematic observer gain calculation that facilitates the use of gain scheduling to improve the transient response of the observer over a wide speed range and improve the low speed performance of the closed-loop sensorless controller. Laboratory experiments are used to demonstrate these improvements.
