摘要
在分析永磁同步电动机(PMSM)数学模型的基础上,利用Matlab/Simulink搭建了PMSM矢量控制系统仿真模型,系统采用速度、电流双闭环PI控制。该模型采用转子磁链定向控制实现解耦,逆变器模块采用电流滞环和空间电压矢量(SVPWM)两种不同的开关控制方案。仿真结果验证了转子磁链定向控制方法的有效性,同时对不同开关控制方案时系统的性能差异进行了比较分析。
Based on the mathematical model of permanent magnet synchronous motor （PMSM）, a system of modeling and simulation of PMSM was constructed by Matlab/Simulink, and two PI controllers were used in the speed loop and current loop. Field oriented control technology were adopted for decoupiing, and two different methods including hysteresis current control and SVPWM were used to control the inverter. The reasonability and validity were testified by the simulation results. Performance responded to the different feeding methods were described as well as the reasons have been discussed.
