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

摘要

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.
