摘    要:内置式永磁同步电动机适合电动汽车牵引驱动,为了满足车用驱动控制系统的动、稳态性能和鲁棒性,设计一种模糊滑模变结构直接转矩控制策略。该方法克服了传统直接转矩控制存在转矩脉动、速度超调、抗干扰能力差的不足,减弱了滑模变结构控制的颤振问题。仿真试验表明该方法具有可行性和有效性。

Abstract: In order to meet the vehicle drive control system dynamic and steady state performance and robustness, a fuzzy sliding mode variable structure and direct torque control strategy was designed to interior permanent magnet (IPM ) synchronous motor which fits the electrical vehicle driving. This method overcomes the existence of conventional direct torque control torque ripple, speed overshoot and poor anti-disturbance ability, and weakens the serious chatting which exists in sliding mode variable structure control. The simulation results show the feasibility and effectiveness.
