LAAS at Toulouse - an overview / Preliminary results about anti-windup strategy for systems subject to actuator and sensor saturations

Back
Abstract:
This paper addresses the problems of the design of anti-windup schemes for linear systems subject to amplitude limitations in actuator and sensor. The design of anti-windup loops, using both measured and estimated variables, is considered in order to enlarge the region of stability of the closed-loop system, whereas some performance in terms of bounded controlled output is guaranteed. Based on the modelling of the closed-loop saturated system including the observer loop as a linear system with dead-zone nested nonlinearities, constructive stability conditions are formulated in terms of linear matrix inequalities by using Finsler's Lemma. Keywords: Anti-windup scheme, actuator and sensor saturations, observer, stability regions, LMI ----
