The Simplified Control Technique for PMSM Torque Ripple Reduction

High precision positioning applications realized with a permanent-magnet synchronous motor are in demand on the market. The paper is concerned with the simplified control technique for such applications to reduce two significant challenges the flux harmonics and a cogging torque. The proposed control enhancing the tracking position accuracy for low-speed servo drives is based on well-known approach using the parallel connection of several resonant terms in parallel manner with a conventional speed proportional-integral (PI) controller. Finally, the experimental results show viability and effectiveness of high-performance tracking operations through eliminating of the selected speed pulsations.
