| 摘 要： | 依据永磁同步电机直接转矩控制理论,采用矢量细分的控制策略和SVPWM调制方法,将原6个电压矢量和6个磁链扇区细分成12个电压矢量和12个磁链扇区,并分析不同电压矢量在每个定子磁链扇区内对转矩的作用,在此基础上,引入零矢量的插入,提出新的电压矢量开关表,利用MATLAB软件进行仿真,理论分析和仿真结果表明这种控制策略可以在很大程度上减小转矩脉动,具有更好的动静态性能.

| Abstract: | The reasons for the torque ripple and poor low speed performance in the conventional direct torque control technology lie in the stator flux range and flux change contradiction within the conventional switch table.The theory of DTC in PMSM introduce vector subdivision control strategy and svpwm modulation method are utilized,so that six voltage vectors and six magnetic chain are subdivided into twelve voltage vectors and twelve magnetic chain.The effects of the different voltage vectors in the stator flux s... |
