摘要
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。
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.
