| 摘 要： | 传统的直接转矩控制(DTC)会不可避免地产生转矩脉动,只适用于调速要求不高的场合.针对该问题,设计了一种模糊控制,优化电压矢量的选择,改善磁链和转矩的综合性能,提高系统的动态响应.通过实验装置对该控制策略进行前后对比研究,结果表明模糊型异步电机DTC比传统的DTC转矩脉动小,而且磁链圆也得到改善,提高了系统的性能,证明...

| Abstract: | Due to conventional direct control has to product the torque ripples,then it is only used to situation which need not perfect speed regulation.This paper proposes a kind of fuzzy control,in order to optimize the select of volt-age space vector,reform the performance of flux and torque and improve dynamic response of the system.In contrast to other control strategies,DTC based on fuzzy control enjoys lower torque ripples and better flux trajectory,improve the system performance which prove the method effect. |
