Abstract

The windup phenomenon appears and degrades control performance when a controller with integrating action is used and the plant input is limited. An anti-windup integral-proportional (IP) controller is proposed for the variable-speed motor drives and it is experimentally applied to the speed control of a vector-controlled induction motor driven by a pulse width modulated (PWM) voltage source inverter (VSI). The consistency range of the IP controller is firstly derived and the integral state is controlled to satisfy always the consistency range according to whether the controller output is saturated or not. Although the operating condition like motor load or speed command is changed under the limited plant input, it is experimentally verified that the speed response has much improved performance, such as no overshoot and fast settling time, and the maximum plant input is also effectively utilized.
