摘要
针对Ranjan等提出的具有分岔和混沌行为的TCP-RED非线性离散模型,从混沌控制角度出发,提出了一种迟滞反馈控制方法,通过对系统参数施加扰动,得到了使路由器缓存中的平均队列长度稳定在原系统的平衡点处的充要条件,从而可获得较高的资源利用率和有界的时延等。最后通过数值仿真验证了该方法的有效性。
Aiming at a TCP-RED non-hnear discrete model with complex bifurcating and chaotic behavior from Raujan, this paper proposes a delayed feedback control method for controlling chaos in Internet congestion control system. A necessary and sufficient condition is presented, which can make the average queue length in the buffer of the router can be stabilized at the fixed point in the original system, and then higher resources utilization and bounded delays etc. can be obtained. The efficiency of this method has been proved by numerical value.
