A design method of a static anti-windup controller constructed from a left coprime factorization of the original linear controller is proposed. A performance index is derived based on the observation that the overshoot of the step response becomes smaller as the magnitude of the input to the saturation function is made smaller during saturation. The minimization of the performance index is represented as H2 or H∞ control problems with state feedback. The result is extended to a class of controllers which have feedthrough term by applying singular perturbation method. Two parameters contained in the performance index are chosen to improve not only anti-windup property but also robust stability.
