TCP/AQM network congestion prescribed performance event-triggered control with input saturation

In this paper, the overall window model is used to describe the network operation for networks under TCP protocol, taking into account the interference of UDP streams and http streams to the network operation process. Based on this model, taking into account the input range of the network packet loss rate, processing the impact of input saturation on the control effect and introducing a prescribed performance method, designing an event triggering network congestion controller. The designed controller can track the queue to the preset value and has certain transient and steady-state performance. Finally, the effectiveness of the controller is verified by simulation.
