摘要：
A robust PM non-fragile control mechanism is introduced in order to the control TCP/AQM network. The TCP/AQM linear system is described based on network dynamic model. A PID controller is proposed to adjust network queue congestion. The close-loop system transfer function is transferred to a high-dimension linear time-delay system. Consider the system disturbance and control structure error, the stability of time-delay system is analyzed, and a stability criterion is obtained with some conservatism. The sufficient condition is given to judge the stability of TCP/AQM based on linear matrix inequality (LMI). Then the controller parameters are solved by LMI. Finally, an example is given to illustrate the feasibility of the proposed method.
