摘　　要：为了解决开关磁阻电机(SRM)调速系统中模糊控制(Fuzzy)策略存在静差的缺点,提出了模糊-PI(Fuzzy-PI)复合控制策略。以速度误差、速度误差变化作为系统外环的输入,大误差和小误差分别采用模糊控制和PI控制不同的控制方法。内环的输入目标转矩由外环的输出提供,最终送到SRM调速系统中。仿真结果得出,Fuzzy-PI控制解决了常规方法中模型建立困难导致控制参数确定困难等缺点。模糊控制本身也存在静差和抗干扰能力弱等问题。Fuzzy-PI复合控制策略在SRM上的应用,是电机调速驱动系统的进一步发展,具有很大的研究意义。In order to solve the problem of switched reluctance motor （SRM） fuzzy control systems （Fuzzy） strategy has static difference shortcomings, a Fuzzy -PI （Fuzzy-H） composite control strategy is put forward, in order to speed error, speed error change as the system outer loop input, large error and small error by using fuzzy control and PI control in different ways. Enter target torque provided by the output of the outer ring, and ultimately to the SRM speed control system. The simulation results show that, the Fuzzy-PI control solution of the conventional method of model leads to disadvantages of difficulty very difficult to determine the control parameters. The fuzzy control itself has problems of static error and weak anti-jamming capability. Application of Fuzzy-PI compound control strategy in SRM, it is a further development of motor drive system, has a great significance.
