摘要

网络拥塞控制系统非线性动态模型的分析与控制是近年来研究的热点问题。本文研究了包含TCP和AQM的互联网拥塞控制系统类TCP模型的分岔行为。特别地，系统参数对非线性动力学行为的影响以及倍周期分岔和混沌发生的条件将被揭示。然后提出一种自适应控制器来控制系统的混沌。该控制器是基于模型参考自适应系统(MRAS)方法的线性化时滞系统控制器。仿真结果表明，该方法可以有效地控制系统的复杂行为。

Analysis and Control of Bifurcation and Chaos in TCP-Like Internet Congestion Control Model

Analysis and control of nonlinear dynamical models of Internet congestion control system has been an interested issue in recent years. In this paper the bifurcation behavior of the TCP-like model of Internet congestion control system including TCP and AQM is investigated. In particular, the effects of system parameters on nonlinear dynamical behavior and the condition for period-doubling bifurcation and chaos occurrence will be revealed. After that an adaptive controller will be proposed for controlling chaos in this system. This controller is based on model reference adaptive system (MRAS) method for a linearized system with delay. Simulation results demonstrate that the complex behavior of the system can be controlled by our method.
