Abstract

This paper presents the sliding mode observer for sensorless control of the interior permanent magnet synchronous motor (IPMSM) drives. The sliding mode observer has been presented as a robust estimation method. Most of previous these works, however, were not for interior PMSM (IPMSM), but for non-salient pole PMSM and its observer design is conducted in the stationary reference frame. Thus, in this paper, we investigate the design of the sliding mode observer and its driving characteristics for the IPMSM. The proposed sliding mode observer is designed in the rotating reference frame, and good drive performance is achieved even the observer parameters are mismatched with those of actual motor. The proposed method is applied to a 600W IPMSM, and then the measurement results are presented.
