Abstract

In this paper, an improved sliding mode observer (SMO) is proposed to guarantee the position detection accuracy of the permanent magnet synchronous motor (PMSM) developed for magnetic suspension molecular pumps (MSMP). Since the traditional SMO based sensorless scheme has chattering problems, and considering the existence of harmonics component, the estimated back-EMF waves should be further processed. For this reason, a novel back-EMF observer is proposed to extract the fundamental wave of the estimated back-EMF signals. Experimental results show the effectiveness of the proposed sensorless control of PMSM.
