A Modified Direct Torque Control Based Fuzzy Variable Structure of Permanent Magnet Synchronous Motor

Article Preview

Abstract:

For getting the High-performance electric vehicle control which has good dynamic, static characteristics and robustness, a direct torque control strategy of fuzzy sliding mode variable structure was designed to IPM motor. The method changes torque ripple, speed overshoot, poor anti-disturbance ability of the conventional DTC, and weakened the serious chatting which existed in sliding mode variable structure control. The simulation results show the feasibility and effectiveness.
