摘　　要：研究了双路由TCP/AQM网络系统的拥塞控制问题。基于单路由TCP/AQM网络系统窗口模型,构建了遵循“优先选择,随机转移”数据包传输规则的双路由TCP/AQM网络系统模型。经过一类状态变换,得到了具有下三角形式的非线性系统状态空间模型。采用逆推设计方法,提出了针对双路由网络系统的主动队列管理拥塞控制算法。设计了使TCP/AQM网络系统渐近稳定的状态反馈控制器。仿真结果验证了所提方法的可行性和有效性。The congestion control for bi-router TCP/AQM network system is studied in this paper.Based on the window model of single-router TCP/AQM network system,a model of bi-router TCP/AQM network system is constructed,which follows the data packet transmission rules of priority selection and random transfer.By using a class of state transformation,the state space model of a nonlinear system with lower triangle form is obtained.An active queue management congestion control algorithm for bi-router network system is proposed by using the backstepping design method.A state feedback controller is designed to make the TCP/AQM network system asymptotically stable.The simulation results verify the feasibility and effectiveness of the proposed method.
