In this paper, the authors consider the phenomenon of congestion of a router in a communication network, initially, they propose a model of TCP based on the fluid flux model and secondly, they propose a synthesis of an observer and state feedback to stabilize the system. In this paper, they have taken into account both the time variant delay and the perturbations due to UDP flow. Such traffic control will be implemented by a mechanism of Active Queue Management (AQM), located at the router.
