In this paper, the design strategy of anti‐windup controller (AWC) for feedback control system is proposed. The proposed method is based on Youla parametrization of linear controllers in the framework of left coprime factorization. Conventional anti‐windup controllers have difficulty in optimization of parameters. The suppression effect of windup phenomena can be adjusted easily with the proposed AWC. The effectiveness of proposed method is shown with some numerical and experimental results. © 2002 Wiley Periodicals, Inc.
