A Frequency Domain Performance Criterion and a Design Technique for Anti-windup Compensators

Abstract

This paper considers an anti-windup compensation in control systems with saturation nonlinearity. The performance specification is based on the output deviation between an idealized system without input saturation and the anti-windup compensated system with input saturation. The proposed design procedure for anti-windup compensators is written in terms of linear matrix inequalities. A numerical design example is provided to illustrate the properties of the resulting closed-loop system.
