摘要:
经过线性化处理的TCP/AQM拥塞控制模型是一个输入带有时滞的源端链路端组合系统。首先修改了带有延迟的网络拥塞控制模型;计算其平衡状态并进行线性化，采用积分变换算法进行延迟变换为无时滞的线性模型，并建立相应的状态空间模型。在模型矩阵参数抖动但有界限的条件下，应用变结构控制算法设计控制器，基于李雅普诺夫稳定性理论和线性矩阵不等式方法给出了该控制器控制的系统可到达和渐进稳定的可行条件，同时根据该条件设计网络链路端主动队列管理算法。最后，仿真结果表明了该算法的有效性。
Abstract:
The linearization model of transmission control protocol(TCP)/active queue management (AQM) dynamical model is a source end and linking end (nonlinear) input complex system with time delay. Firstly a network congestion control model with delay was modified, the equilibrium of which was calculated and linearized. The model was transformed into a linear model without time delay via an integral sliding mode control(ISMC) technology (integral transformation algorithm). A corresponding spatial model was constructed. A controller was designed by variant structure algorithm under the condition of the mismatched but bounded perturbation of model matrix parameters. Based on the Lyapunov theory and linear matrix inequality (LMI) method, feasible conditions to ensure that the sliding surface (the system) can be reachable with asymptotic stability was presented. The active queue management arithmetic was devised by the feasible solution, the effectiveness of which was validated by the MATLAB simulation result.
