Abstract :
Aiming at the nonlinear model of TCP network, we carried out a T-S fuzzy model with uncertain parameters which can describe the AQM more approximate; In addition, we achieved the sufficient condition for the existing of minimax controller with considering the situation that the system got the max impact when being disturbed by LMI and Liapunov stability theory. The simulation showed the control algorithm we proposed had better stability and robustness as well as dynamic performance that the message queue length being converged to the expected value more quickly.
