Design of robust H-infinity controllers for congestion control in data networks

摘要

A novel approach for internet congestion control is presented here, using a static feedback law. A congestion controller for Network TCP/ IP Routers is derived, to ensure stability for a large set of admissible initial conditions. From a formal point of view, we propose a static state-feedback for discrete-time delayed systems, with both saturating inputs and link capacity disturbances, that ensures simultaneously closed-loop stability and a prescribed level of performance. The effectiveness of the proposed approach is verified via simulation, comparing the results to PI and RED controllers. (C) 2017 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
