In the control of actual plant, there commonly exits a constraint on the control input caused by mechanical constraint on the actuator or to protect the plant. This constraint usually exerts adverse effect on control performance called windup phenomenon. Anti-windup technique is known as one of the most effective techniques to prevent such windup phenomenon.
In this paper, we propose a new design of anti-windup controller based on state feedback H∞ control theory. This design consists of representation of anti-windup controller that includes a free parameter and decision of the free parameter by using state feedback H∞ control theory. Then, we also discuss the problem on discretization of anti-windup controller in implementation. In numerical case study, we demonstrate the performance of proposed anti-windup controller by computer simulation.
