摘要:
根据主动队列管理算法中TCP拥塞窗口的流体流模型,给出了离散模型和广义预测控制(GPC)算法的表达式;得出了路由器输出队列长度与参考队列长度的闭环传递函数;证明了GPC控制器在满足特定控制参数的条件下,无论网络参数如何变化,闭环系统都是稳定的;并通过仿真验证了其正确性.
Abstract:
The discrete network model and the expression of Generalized Predictive Control(GPC) controller are educed based upon the fluid-flow model of TCP congestion window. Then the closed loop ransfer function of muter’s output queue length and referenced queue length are obtained. It is proved that the closed-loop systems is stable no mater how the network parameters chancing,if some specific constraints of GPC controller’s parameters are satisfied. Finally,the validity is verified by a simulation.
