Abstract

Abstract: With the aim of improving the performance of the vector controlled induction motor system, a novel control method which combines variable structure PID speed control with online identification of rotor resistance based on model reference adaptive system (MRAS) is proposed. The rotor resistance is identified by self-adaptive adjustment in the model reference adaptive system based on the instantaneous reactive power. Given that the parameters can not change on line and the integral saturation phenomenon often exists in traditional PID speed regulator, a variable structure PID speed controller is designed by integrating anti-windup technology with fuzzy theory based on traditional PID controller. It can be seen from the MATLAB simulation experiment that the proposed controller can reduce the integral windup phenomenon of the system and minish speed overshoot. The effectiveness of rotor resistance identification based MRAS is proved in variable structure PID speed control.
