摘　　要：电动车用电机要求驱动系统具有较好的起动加速特性、较宽的调速范围和再生制动能量回收功能等。开关磁阻电机驱动控制是一种极有潜力的电动汽车驱动系统,可以提升电机调速性能和抑制转矩脉动,但SRM的非线性特性造成了SRM在工作时的转矩波动大,噪声和振动问题严重。为改善开关磁阻电机的非线性特性问题,提高开关磁阻电机调速系统的响应特性和稳定性,将传统模糊控制和PI控制技术结合应用到转速控制器的设计中。在MATLAB/Simulink环境下搭建开关磁阻电机调速系统模型,基于仿真分析,搭建了模糊PI控制系统,并将其与电流、转速双闭环调速控制系统和速度PI控制系统进行对比,仿真结果表明,模糊PI控制具有起动快、稳定性好和抗干扰能力强等优点,更适用于开关磁阻电机的调速控制。Electric vehicle motor drive system requires good start acceleration characteristics, wide speed range and regenerative braking energy recovery function, etc. Switched reluctance motor drive control is a very promising e- lectric vehicle drive system and can improve the speed tracking performance and reduce the torque ripple, but the nonlinear characteristics of SRM caused the SRM torque ripple, loud noise and vibration problems serious at work. In order to improve the switched reluctance motor problem of nonlinear characteristics, as well as the switched reluctance motor drive system response characteristics and stability, traditional fuzzy and PI control methods were investigated. Based on MATLAB/Simulink, we built the model of switched reluctance motor drive system. And based on the simu- lation analysis, we established the system of fuzzy PI control. The current and speed double loop control system was compared with speed PI control system. Simulation results show that the fuzzy PI control with a quick start, good sta- bility and strong anti-jamming ability, is more suitable for controlling the speed of switched reluctance motor.
