摘  要：永磁同步电机矢量控制技术在工业界得到了广泛的应用。矢量控制可以采用电压法和电流法实现。前者采用SPWM技术生成逆变器开关信号，后者采用电流滞环控制技术生成逆变器开关信号。本文在表面式永磁同步电机和内置式永磁同步电机矢量控制平台上对这两种实现方法进行实验，在实验结果基础上分析比较了两者的控制特性。

Abstract: The field oriented control (FOC) for permanent magnet synchronous motor (PMSM) is widely used in the industry. The FOC can be implemented by using the voltage method or the current method. The voltage method uses the sinusoidal pulse width modulation (SPWM) to generate the switching signals of inverter and the current method uses the hysteresis current control to generate the switching signals. The performances of these two ways were proposed based on experimental results of surface PMSM and interior PMSM.
