摘要：
The tracking control problem for the TCP/AWM network system with nonresponsive user datagram protocol flows is studied. A modified network model is given for network congestion control system. With the aid of prescribed performance control and event-triggered mechanism, a novel AWM congestion control algorithm is proposed. The queue tracking error of the TCP/AWM network system is limited by an improved boundary performance function, which improves both the transient and steady state performance of the closed-loop system, and guarantees that all closed-loop signals are bounded. Besides, the event-triggered control protocol based on 1-bit signal transmission only requires a binary signal (0 or 1) to transmit information when control signal is updated. Compared with the traditional event-triggered control protocol, this protocol considers not only the limited bandwidth, but also the cost and security of network transmission. Finally, a simulation result is shown to clarify the feasibility and effectiveness of the proposed approach. © 2023 South China University of Technology. All rights reserved.
