中文摘要
      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.
英文摘要
      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/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.
