Dazhong Wang, Shujing Wu · Mathematical Problems in Engineering · 2014
The purpose of this paper is to design congestion controller for TCP/AQM (transmission control protocol/active queue management) networks using model following control; the equilibrium of a class of TCP/AQM networks with time‐delay is investigated, and the effect of communication time‐delay on the stability is addressed. The features of this design method are bounded property of the internal states of the control system being given and the utility of this control. Such design exhibits important attributes including fast convergence with high accuracy to a desired queue length. Simulation results show that the time‐delay nonlinear behavior of the system can be controlled by this method.
