电流型变频调速系统抑制转矩脉动的研究

Elimination of Armature—Moment Ripple in Current Type Speed Control System with Variable Frepuency

本文提出了一种电流型变频调速系统抑制转矩脉动的方法。利用转矩测试装置不仅能够观察脉动的大小;而且还可通过调制直流回路电流达到抑制转矩的脉动,实验获得了满意的结果。

A method for eliminating the ripple of armature moment in a current type speed control system with variable frequency is put forward in this paper.The ripple of armature moment is observed by means of arma- ture-moment-testing devices.Furthermore,the ripple may also be eliminated by modulating the current in D.C.circuit.A satisfactory result has been obtained in experiments.
