采用SVPWM的永磁同步电机伺服系统建模与仿真

Modeling and simulation of PMSM servo system using SVPWM

分析了永磁同步电机速度伺服系统的控制原理,着重介绍了空间矢量脉宽调制(SVPWM)原理,并利用Matlab/Simulink工具箱搭建了系统仿真模型该方法和传统的正弦脉宽调制方法相比具有更高的电压利用率.仿真结果验证了该模型的正确性和有效性,并为实际PMSM伺服系统设计提供了参考和依据.

This paper analysed the control principle of servo system of permanent magnet synchronism motors （PMSM）. Specially the principle of space vector pulse width modulation （SVPWM） was discussed. The simulation model was established using Matlab/Simulink toolbox. SVPWM has a higher voltage using rate. The effectiveness and correctness of the model was verified by the simulation results, thus offering a useful reference and basis for the design of actual PMSM servo system.
