基于SVM-DTC的永磁同步电动机控制方法研究

摘要

In this paper, permanent magnet synchronous motor (PMSM) direct torque control (DTC) system was studied. For inhibiting the ripple of torque and flux linkage of traditional control systems, the PMSM- DTC system was combined with the space vector modulation (SVM). Based on the study with the mathematical model of PMSM and SVM, and simulated the system in Matlab/Simulink. The system model has been proved reasonable and effective with good dynamic and static performance.%研究永磁同步电机(PMSM)直接转矩控制(DTC)系统.针对传统控制系统中存在的转矩和磁链脉动大的问题,将空间矢量调制(SVM)引入PMSM-DTC系统.通过对永磁同步电机数学模型及空间电压矢量调制算法的分析,在Matlab/Simulink环境下,对PMSM的SVM-DTC系统进行仿真.仿真结果表明、系统模型具有很好的动静态性能.
