| 摘 要： | P I控制器常用于主动队列管理中,但参数整定上的试凑法具有盲目性,算法的瞬态性能也不够理想。本文针对TCP网络系统的时滞特性,设计基于内模补偿控制器,提出了基于幅值与相位稳定裕度的控制参数整定方法。仿真实验表明,与P I算法相比较,该方法设计的控制器的稳定性与鲁棒性有显著的提高。

| Abstract: | PI controller is used to control queue length of active queue management.But its trial method of controller tuning is aimlessness,the instant performance of algorithm is not enough satisfied.The internal mode compensation controller is designed for the delay performance of TCP network system.The controller tuning method is presented based on the gain and phase margin.Simulation experimental results show that the stability and the robustness of the networks with the design method is obviously superior to that of PI schemes. |
