Simple globally stabilising anti-windup designs for systems with rate-limits

Simple globally stabilising anti-windup designs for systems with rate-limits
Simple globally stabilising anti-windup designs for systems with rate-limits

This paper develops an anti-windup scheme for stable linear systems subject to rate-limited control inputs. The main contribution of the paper is a simple condition that guarantees the existence of a family of globally stabilising anti-windup compensators. The approach is a natural development of an existing, tried-and-tested scheme, with the supplemental property of global asymptotic stability. It is also shown that IMC-like anti-windup compensators appear as special cases of the more general design procedure and, moreover, that these compensators guarantee external, as well as internal, stability. An example illustrates the results.

Abstract

This paper develops an anti-windup scheme for stable linear systems subject to rate-limited control inputs. The main contribution of the paper is a simple condition that guarantees the existence of a family of globally stabilising anti-windup compensators. The approach is a natural development of an existing, tried-and-tested scheme, with the supplemental property of global asymptotic stability. It is also shown that IMC-like anti-windup compensators appear as special cases of the more general design procedure and, moreover, that these compensators guarantee external, as well as internal, stability. An example illustrates the results.
