Abstract

The windup phenomenon appears and results in performance degradation such as large overshoot, slow settling time when the integral-proportional (IP) controller output is saturated. An anti-windup IP controller is proposed to improve the control performance for the motor drives. The proposed algorithm is applied to the current control of a vector-controlled induction motor driven by a pulse width modulated(PWM) voltage-source inverter. The integral state is separately controlled corresponding to whether the IP controller output is saturated or not. The experimental results show that the current response has much improved performance such as little overshoot and fast settling time.
