摘　　要：为了改善电动汽车驱动系统的性能，提出了一种感应电动机的模糊转矩控制系统。系统选用电机定子磁链误差、电机电磁转矩误差及磁链位置角作为模糊变量，利用模糊逻辑选择开关状态，有效地提高了系统暂态时转矩响应。仿真结果证明，本文提出的控制方法保证电机高效、稳定、快速地产生电磁转矩。通过比较模糊转矩控制系统和直接转矩控制系统，模糊转矩控制系统更适合作为电动车驱动系统。A fuzzy torque control system for induction motor is developed in order to improve the performance of electric vehicle drive system. Utilizing the stator flux error, electromagnetic torque error and flux position as fuzzy variables, and fuzzy logic for choosing the switching states, this system improves the electromagnetic torque response of the system effectively in transient states. The simulation results demonstrate that the presented control method ensures an induction motor generates the motor torque efficiently, stably and accurately. By comparing the developed system with conventional direct torque control (DTC), fuzzy torque control (FTC) is more suitable for the drive system of electric vehicles.
