摘要： 针对TCP网络的有限时间拥塞控制问题，考虑到输入受限、网络参数不确定和非响应流干扰的情况，提出了一种基于自适应终端滑模控制的主动队列管理算法.为了使网络系统不确定的界不需要事先获得，给出一个自适应律对总不确定的界进行了估计.考虑到系统输入受限的情况，给出另一个自适应律以补偿输入受限对系统稳定性造成的影响.为了改善网络系统的收敛性能，基于终端滑模控制设计了一个有限时间拥塞控制器.仿真结果表明，所提出的算法不仅具有有限时间收敛的品质，而且具有良好的稳定性和鲁棒性.

Abstract: To solve the problem of finitetime congestion control for TCP networks with input constraint， network parameter uncertainties and nonresponsive flow disturbances， an active queue management algorithm was presented based on an adaptive terminal sliding mode control. One adaptive law was designed to estimate the certainty bound of the network system so that the certainty bound was not required to be known in advance. Another adaptive law was proposed to compensate for the effects of the system stability under control input saturation. A finitetime congestion controller based on terminal sliding mode control was designed in order to improve the convergent performance of the network system. Simulation results showed that the proposed algorithm not only has the property of finitetime convergence but also has good stability and robustness.

Key words: congestion control, active queue management, input constraint, terminal sliding mode control, finitetime control
