SMC Strategy for Torque Ripple Mitigation in Permanent Magnet Synchronous Motor

This paper presents a new extended control of the sliding mode of the permanent magnet synchronous motor with various uncertainties. This extended scroll mode control can dynamically adapt to changes in the controlled system and maintain high tracing performance of the extended scroll mode controller. The extended control of the sliding mode is proposed to compensate for strong disturbances and obtain high servo precision. Sliding mode control is proposed for estimating rotor speed and stator resistance, assuming that only stator currents and voltages are available for measurement. The results validate the effectiveness of the proposed method through simulation
