Abstract

A multiloop feedback control system supplemented by a complementary controller is used to improve the drive performance of an AC induction servo motor and to reduce sensitivity to parameter variations, nonlinear effects, and load disturbances. Based on the principle of field-oriented vector control, a software-based current-decoupled controller has been proposed. A simplified model of the current-decoupled induction motor has been used for the design and simulation of the proposed robust controller. Experimental results based on multimicroprocessor implementation are presented to illustrate improved response and reduced sensitivity.<>
