Active queue management algorithm based on T-S fuzzy control

A novel T-S fuzzy control algorithm is presented for active queue management(AQM) in order to solve the problem of congestion control in TCP communication. This kind of control action has robust performance, which is suitable for time varying and complex network systems. For the particular TCP network mode, a T-S fuzzy model is done for the nonlinear TCP/IP network congestion control system. The performance of network congestion control system is improved by choosing appropriate fuzzy rules and membership functions, and the stability of the system is rigorously theoretic proved. The stability and robustness of the proposed control scheme are then validated for different network scenarios in MATLAB. Simulation results have confirmed that the proposed scheme outperforms traditional observer-based controller.
