| 摘 要： | 当前Internet拥塞控制系统中,作为闭环拥塞控制系统的校正控制器,采用了AQM(Active Queue Management)控制器技术;AQM控制器中通常采用RED(Random Early Detection)算法,但RED算法存在一系列缺点;文章在校正控制器的设计中,采用状态反馈控制算法,以提高Internet拥塞控制系统的控制性能。内容包括:被控制系统模型、状态反馈控制器设计及状态变量测量等问题;最后通过NS2平台上的仿真计算,验证了所提出方法在动态性能上优于RED算法。

| Abstract: | Recently,AQM(Active Queue Management) controller has been applied to the Internet congestion control system as the compensator of the feedback control system.RED(Random Early Detection) algorithm is widely adopted by AQM controller,however,RED emerged some drawbacks.In this paper,the state feedback control algorithm is applied to AQM controller in order to improve the control performance.The design of state feedback controller(SFC) is systematically presented,including the model of controlled system,the des... |
