Abstract
It was recently shown that certain instances of the natural anti-windup problem necessarily lead to control systems lacking "robust in the large" stability, and that in such instances it is meaningful to solve a weakened anti-windup problem (trading performance for robust stability). While previously proposed solutions of the weakened problem essentially require state feedback, this paper provides output feedback solutions for the case of additively perturbed systems.
