摘要：

Aiming at the congestion control problem for TCP/AWM network system, an arbitrary convergence time congestion controller based on the disturbance observer is proposed in this paper. Firstly, in order to make the output signal track the expected queue within settling time, the free-will arbitrary time control (FATC) is used to design the equivalent controller. In addition, the super twisting control (STC) is introduced as the disturbance observer to solve the chattering problem caused by the traditional signum function, which results that the switching control is changed from discontinuous control to continuous control. Finally, all closed-loop signals are free-will arbitrary time stable. Simulation results show the effectiveness of the proposed control scheme.
