AB This paper addresses the design of anti-windupgains for obtaining stability for linear systems with discretetime varying delay and saturating inputs delay. Consideringthat a dynamic output feedback has been designed to stabilizethe AQM system (without saturation), a method is proposed fordesigning an anti-windup gain which relates the saturation ofthe queue when congestion, which is inevitable in networks. It isshown that the closed-loop system obtained from the controllerplus the anti-windup gain can be modeled by a linear systemwith a dead zone nonlinearity. A modified sector condition isthen used to obtain stability conditions based on Lyapunovfunctions. Differently from previous works these conditions aredirectly in linear matrix inequality form. Resulting in a newAQM which will be simulated in MATLAB and compared toRED.
