H ∞ Dynamic Output Feedback Control for TCP/AQM Network Systems
Pengfei Ma, Linlin Hou, Haibin Sun · 2023
The problem of H∞dynamic output feedback control is studied for TCP/AQM network congestion systems in this paper. First, the TCP network system is modeled as a T-S fuzzy system with time-delay and disturbances. Then the dynamic output feedback controller is designed to guarantee the exponential stability of the studied system. By applying Lyapunov-Krasovskii function approach and the linear matrix inequality technique, the results about the exponential stability and H∞performance are obtained. Finally, simulation results show that the proposed control strategy is effective.
