Kharitonov approach and padé approximation applied to the robust controller design of active queue management routers for internet protocol

Several studies have considered control theory tools for traffic control in communication networks, as for example the congestion control issue in IP (Internet Protocol) routers. In this paper, we have two main goals: the first one is to obtain a controller which approximates the true system containing a delay; this will be ended by choosing the adequate degree of Pade approximation. Our second goal is to attain a robust AQM (Active Queue Management) controller coping with uncertainties on the network parameters and this, by using Kharitonov approach.
