交流电机直接转矩控制改进方案

Overview of the improved schemes of AC motor direct torque control

从直接转矩控制的原理出发,介绍直接转矩控制减小脉动方法以及特点。虽然这些方法在一定程度上可改善直接转矩控制性能,但增加系统的复杂性。提出改善直接转矩控制性能而不增加系统复杂度,则是未来的研究重点。

Basing on the theory of direct torque control,this paper discusses the methodalogy for flux and torque ripple reduction in induction motor direct torque control. Each method can improve the performance of direct torque control, but all increase the system complexity.It is the study core that not only improve the direct torqhe control performance,but also reduce the system complexity.
