Abstract

This paper proposes a dynamic compensation scheme for input-constrained linear systems to cope with the windup phenomenon. Given a linear controller for such a linear system designed without considering its input constraints, an additional dynamic compensator is proposed to account for the constraints. This dynamic anti-windup scheme is based on H_∞ optimization, and some stability properties of the resulting closed-loop system are given.
