基于12扇区的PMLSM直接推力控制
|
摘要
针对永磁直线同步电机(PMLSM)传统6扇区直接推力控制推力脉动大的问题,提出了基于12定子磁链扇区和13电压空间矢量的直接推力控制方法,设计了一种新的电压选择开关表,利用三相和两相混合导通方式,实现13电压矢量输出,利用Matlab/Simulink对永磁直线同步电机12扇区直接推力控制系统进行了建模与仿真研究。仿真结果表明,与传统的直接推力控制方法相比,改进的12定子磁链扇区直接推力控制可以明显减小推力和磁链脉动,性能优越。
To deal with the defect of thrust ripples of the traditional six section direct thrust control(DTC) for permanent magnet linear synchronous motor(PMLSM), a novel DTC strategy of PMLSM combined 12 stator flux linkage sectors and 13 voltage space vectors is proposed. A novel voltage selection table is designed. The way of three and two devices conducting interactively is applied to realize 13 voltage space vectors. The method is simulated through Matlab/Simulink. The results of simulation verify the better performance of the twelve-section control method, which can reduce the thrust and flux linkage ripple.
