基于不确定时滞模型的鲁棒AQM控制器设计

Abstract

Abstract: To describe the uncertainness of network environment and the time-varying property of network parameters,an uncertain time-delay system model is established to carry out research on network congestion control.The sufficient condition is given to judge the stability of the active queue management(AQM) system by linear matrix inequality approach,and a method is also given to set parameters of an AQM controller based on nonlinear matrix inequality.The time-delay static output feedback controller is proposed based on linear matrix inequality.Simulation result shows that the controller designed by this approach is effective,and its dynamic response is faster and smoother in variable network condition.
