A Study on Driving Algorithm of Single-phase PMSM based on Proportional Resonant Current Controller

Abstract

In this paper, an operating algorithm for single-phase permanent magnet synchronous motor based on PR current controller is proposed. In general, an asymmetric gap may occur depending on the shape of the rotor of single-phase PMSM, and this causes noise and vibration during high-speed operation. Therefore, in this paper, an operating algorithm for a single-phase PMSM usihng a proportional resonant current conrtoller with excellent control stability was proposed. Proportional resonant current controller has on steady state error is relatevly robust against distortion. Also, steady state error of AC input can be eleminated without complicated calculation process. The validity and availability of the proposed algorithm are
