개선된 슬라이딩 모드 제어기를 이용한 엘리베이터용 SPMSM의 위치제어

In this paper, position control method using improved sliding mode controller for SPMSM in elevator system is proposed. Since the improved sliding mode controller has a feature following prescribed sliding trajectory, it is robust in parameter fluctuation and able to minimize the over shoot. The controller is judged sutiable for the drive system of elevators on the basis of PSIM simulations.
