Sliding mode congestion control algorithm for a class of large-scale networks based on T-S model

This paper is concerned with the sliding mode control for a class of large-scale networks based on a fluid flow model. The nonlinear system dynamic model is represented by a T-S fuzzy model. Sliding mode control approach is employed to guarantee robust stabilization of linear uncertain systems. The stable sliding surface is designed by using linear matrix inequalities (LMI) to reduce the influence of mismatched uncertainties. The sufficient condition for the existence of stable sliding surface is derived in terms of LMI. And the design of sliding mode control law is given too. At last, the simulation results show the effectiveness and feasibilities of the proposed method.
