摘　　要：开关磁阻电动机(SR)的结构不是很复杂,通过其组合成开关磁阻电动机速度控制系统,具有启动转矩大及运行效率高等特点。近年来,开关磁阻电动机调速系统在伺服与调速系统、高速电动机,汽车辅助设备等领域中逐步得到应用,并受到了国内外学者的越来越多的关注。本文采用模糊关断角补偿控制,对抑制SR电动机转矩脉动进行深刻的探究。构建四相SR电动机仿真模型,通过对SR电动机数学模型的分析,表明非线性模型精确反映SR电动机运行特性,提出模糊逻辑关断角补偿控制策略。The structure of the switched reluctance motor(SR)is not very complicated.It is combined into a switched reluctance motor speed control system,which has the characteristics of large starting torque and high operating efficiency.In recent years,switched reluctance motor speed control systems have gradually been applied in the fields of servo and speed control systems,high-speed motors,and automotive auxiliary equipment,and have attracted more and more attention from scholars at home and abroad.In this paper,fuzzy turn-off angle compensation control is used to make a deep research on restraining the torque ripple of SR motor.A four-phase SR motor simulation model is constructed.Through the analysis of the mathematical model of the SR motor,it is shown that the nonlinear model accurately reflects the operating characteristics of the SR motor,and a fuzzy logic turn-off angle compensation control strategy is proposed.
