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.
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.
