In the control of an actual plant, there commonly exists a constraint on the control input caused by mechanical constraint on the actuator or in order to protect the plant. This constraint usually exerts an 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 an anti‐windup controller that includes a free parameter, and decision of the free parameter by using state feedback H ∞ control theory. We also discuss the problem on discretization of an anti‐windup controller in implementation. In a numerical case study, we demonstrate the performance of the proposed anti‐windup controller by computer simulation. © 1998 Scripta Technica, Electr Eng Jpn, 124(1): 33–41, 1998
