ON WEAKENED ANTI-WINDUP AND THE DESIGN OF STATE-FEEDBACK SOLUTIONS

A weakened anti-windup problem was introduced in (Galeani and Teel, 2004) to overcome the robustness limits inherent in the definition of the natural anti-windup problem, and its solution was given in terms of a parameterized family of state-feedback compensators. Two new contributions are presented in this paper. First, a quantitative measure of the performance- robustness trade-off involved in the weakened anti-windup definition is given. Then, a procedure for selecting suitable values for the parameters of the weakened anti-windup compensator is described. Simulations illustrate the effectiveness of the proposed approach.
