Prescribed time sliding mode control for TCP networks with input saturation

This paper studies TCP/AQM network congestion control with user datagram protocol (UDP) interference. Firstly, the problem of input saturation caused by the range of packet loss rate is dealt with. Then, a sliding mode control method with display time term is designed by combining prescribed time with sliding mode, which can effectively avoid the control input singularity problem when the time is close to the prescribed time. Finally, the effectiveness and superiority of the proposed method are proved by simulation and analysis.
