摘　　要：以四开关三相永磁同步电机(PMSM)磁场定向控制(FOC)系统为对象,研究了四开关三相逆变器(FSTPI)空间矢量调制方法,并以此为基础建立系统的控制模型。仿真结果表明:四开关三相PMSM的FOC系统可以稳定运行,并且具有较好的转矩动态响应性能。The field oriented control （FOC） of the permanent magnet synchronous motor （PMSM） fed by the four switch three phase inverter（FSTPI） was studied. The space vector pulse width modulation method for FSTPI was discussed, and three equivalent zero-vector methods were investigated. The control principle of the PMSM FOC sys- tem was discussed as well. Based on the above analysis, the control model for the system was simulated and the re- suits indicated that the FSTPI- PMSM FOC drive system can operate steadily and has satisfied dynamic torque feature.
