Modified dynamic anti-windup through deferral of activation

We consider the dynamic anti-windup design problem for linear systems with saturating actuators. The basic idea proposed here is to apply anti-windup only when the performance of saturated system faces substantial degradation. We provide synthesis LMIs to obtain the gains of the dynamic anti-windup compensator in a structure that delays the activation of the anti-windup. Benefits of the proposed design method over the immediate activation of the anti-windup are demonstrated using a well-known example. Copyright (C) 2011 John Wiley & Sons, Ltd.
