SUMMARY 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 © 2011 John Wiley & Sons, Ltd.
