Abstract

This paper is concerned with the design of improved AQM control schemes. An appropriate robust H^∞ controller for time-delay systems is proposed and hence used to design a suitable AQM control scheme. A robust observer is used to estimate online the transmission window resulting in a novel output feedback stabilization scheme for AQM. The resulting control law is first validated and tested firstly through numerical and experimental methods.
