PMSM-DTC与SVM-PMSM-DTC仿真对比

针对传统PMSM-DTC存在的定子磁链以及转矩脉动问题,将空间矢量调制技术同永磁同步电机直接转矩控制相结合。在Matlab/Simulink以及SimPower System环境下,搭建传统PMSM-DTC仿真系统,同时设计并搭建SVM模块,将其应用于PMSM-DTC系统中。最终仿真结果表明,SVM可以明显的改善定子磁链以及减少转矩脉动。

Comparison of PMSM-DTC Simulation and SVM-PMSM-DTC Simulation

To solve the problem of stator flux linkage and torque ripples in traditional direct torque control （DTC） for a permanent magnet synchronous motor （PMSM）.The combination of the space vector modulation （SVM） with DTC for PMSM was de- signed.Based on matlab/simulink and SimPower System,I build the traditional PMSM-DTC simulation system,design and build the SVM module,and apply it to the PMSM-DTC system.Simulation results show that this method can dramatically im- prove the stator flux linkage and reduce the torque ripples.
