摘要: 针对存在不确定参数和UDP流干扰的TCP网络拥塞问题,提出了一种基于事件触发的TCP网络滑模控制策略.通过利用全局滑模控制方法,使整个系统的响应过程都具有鲁棒性,在此基础上引入事件触发机制,在保证系统状态稳定的同时,节约了网络资源.通过李雅普诺夫理论证明了TCP网络闭环系统里的所有信号是有界的,同时也有效地避免了Zeno现象.仿真结果表明了所提控制方法的有效性.

Abstract: Aiming at the TCP network congestion problem with uncertain parameters and UDP flow interference, an event-triggered TCP network sliding mode control strategy was proposed. The global sliding mode control method was used to make the response process of the entire system robust. On this basis, an event-triggered mechanism was introduced to ensure the stability of the system while saving network resources. The Lyapunov theory proves that all signals in the TCP network closed-loop system are bounded, and the Zeno phenomenon is also effectively avoided. Simulation results show the effectiveness of the proposed control method.

Key words: TCP network; congestion control; AQM(active queue management); event-triggered; sliding mode control
