Abstract
In this study, we apply an anti-windup scheme to the vehicle active suspension system. A fixed-order output feedback controller which does not explicitly take into account the actuator saturation constraint is first designed. Then, an anti-windup compensator is designed to handle the saturation constraint. Local control design technique based on the circle criterion and L2 gain performance is used for the anti-windup compensator synthesis. A quarter car model is considered in this study and the effectiveness of the proposed approach is shown by a numerical example.
