永磁同步电机因其运行稳定、体积小、结构灵活等优点,在空调压缩机、电梯传动、船舶推进以及电动汽车领域都有着越来越广泛的应用。在此根据永磁同步电机的结构,通过数学模型对永磁同步电机进行描述,并在Matlab/Simulink中搭建了一种用于汽车能量回收的矢量控制模型。采用空间矢量脉宽调制技术和速度、电流双反馈的方式,控制永磁同步电机恒转速输出。同时该双闭环永磁同步电机矢量控制能够在高性能电机驱动控制系统方面提供一定的指导意义。

Permanent magnet synchronous motor (PMSM) is widely used in air-conditioning compressor, elevator drive, ship propulsion and electric vehicle because of its stable operation, small size and flexible structure. Accordi ng to the structure of permanent magnet synchronous motor, the permanent magnet synchronous motor is describ ed by mathematical model, and a vector control model for vehicle energy recovery is built in MATLAB/Simulink. The output of permanent magnet synchronous motor (PMSM) at constant speed is controlled by space vector pulse wi dth modulation (SVPWM) and double feedback of speed and current. At the same time, the vector control of doub le closed-loop permanent magnet synchronous motor can provide guidance for high performance motor drive con trol s ystem.
