摘　　要：为实现永磁同步电动机(PMSM)的电压空间矢量控制,在分析永磁同步电动机数学模型的基础上,利用Matlab/Simulink建立了永磁同步电动机矢量控制系统的仿真模型。介绍了矢量控制的坐标变换。重点介绍了电压空间矢量脉宽调制(SVPWM)的控制原理和算法,给出了电压空间矢量脉宽调制在Simu-link环境下的实现方法。最后对整个控制系统进行了仿真研究,仿真结果证明了该控制模型的有效性。For the realization of the voltage space vector control of permanent magnet synchronous motor （PMSM） , on the basis of analysis of the mathematical model of PMSM, the simulation model of vector control system of PMSM was established using Matlab/Silnulink. The coordinate transformation of vector control was introduced. The control principle and algorithms of space vector pulse width modulation（SVPWM） were introduced in detail, and the simulation method of SVPWM was presented. Final- ly, the whole control system was simulated. The simulation results prove the effectiveness of the control model.
