依据直接转矩控制的基本原理,针对永磁同步电动机,分析了电压空间矢量调制的直接转矩控制系统。着重分析了电压空间矢量调制的基本原理,对其算法步骤作了详细的剖析,并给出了各步骤的仿真模型。最后在matlab/simulink环境下对整个控制系统进行了建模与仿真,并对仿真结果进行了分析。仿真结果表明:基于SVM算法的永磁同步电动机直接转矩控制系统的性能得到了改善和提高。
According to the basic principle of direct torque control （DTC） , Focused on the permanent magnet synchronous motor（ PMSM）, the control system of DTC is analyzed based on the space vector modulation （SVM）. To centre on analyzing the basic principle of SVM, a detailed analysis about its algorithm and simulation models of all steps is given, lastly carry out modeling and simulation for the entire system in matlab/simulink environment, and given out a analysis of simulation results. The simulation results show that the performance of PMSM based on SVM-DTC are improved and enhanced.
