摘要
研究了具有非响应用户数据报协议流干扰的TCP/AWM网络系统的跟踪控制问题.针对网络拥塞控制系统,给出了一种改进的网络模型.将预设性能控制和事件触发机制相结合,提出了一种新的AWM拥塞控制算法.利用改进的边界性能函数限制TCP/AWM网络系统的队列跟踪误差,提高了闭环系统的暂态和稳态性能,保证了所有闭环信号都是有界的.此外,采用基于一位信号传输的事件触发控制协议,当控制信号更新时,仅通过一个二进制信号(0或1)传输信息.与传统的事件触发控制协议相比,不仅考虑了有限的带宽,而且考虑了网络传输的成本以及安全性问题.最后,通过仿真验证和分析,证明了所提方法的可行性和优越性.
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/AWMnetwork 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.
