Abstract

In this paper, a nonlinear fluid flow model is used to analyze and control DiffServ Network. Backstepping design procedure is applied, which leads to a new adaptive sliding mode controller. In order to use backstepping design, the model is transformed into a parametric strict feedback form. And by using the adaptive backstepping sliding mode controller, buffer queue length regulation achieved against unknown system dynamics and uncertain disturbances. Under the ideal sliding mode, asymptotic stability is reached. The performance of the control scheme is verified by the simulation results.
