Speed Control of Switched Reluctance Motors Using Sliding Observers

슬라이딩 관측기를 이용한 스위치드 릴럭턴스 모터의 속도제어

In this paper, a new estimation algorithm for the rotor speed for SRM drives is described. The algorithm is implemented by the sliding mode observer. The stability and robustness of the sliding observer for the parameter variations of the SRM are proved by variable structure control theory. Variable speed control of the SRM is accomplished by the estimated speed. Experiment results verify that the sliding mode observer is able to estimate the speed.
