摘　　要：针对在模糊控制多相永磁同步电机系统中,负载端突加负载时不能达到满意的特性,为了得到较优的特性和消除模糊控制时存在的稳态误差,以双Y移30°六相永磁同步电机为研究对象,从建立电机的数学模型入手,为六相永磁同步电机提供了一种基于比例积分和模糊控制的双模矢量控制方法。该控制方法结合了模糊控制和比例积分控制的优点,建立了基于Matlab/simulink的多相永磁同步电机控制系统仿真平台,对双模矢量控制系统进行了仿真。结果表明,该控制方法响应快、无超调、具有较优的动、静态特性。The fuzzy control system could not attain satisfying performance when load is suddeuly added to multiple phase permanent-magnet synchronous motor. In order to get better performance and eliminate static error in the motor control system, the application of double mode vector control scheme which consists of fuzzy control and PI control to is discussed control of dual Y shift 30° six phase permanent-magnet synchronous motor speed. The mathematical model of dual Y shift 30° six phase permanent-magnet synchronous motor is developed on some assumptions. The proposed method combines the strongpoint of both the fuzzy control and PI control. Simulation results show that the proposed control scheme can be effectively used in controlling the speed of six phase permanent-magnet synchronous motor with quick response, no over shoot and high dynamie and statie performance.
