Using input delay approach for synthesizing an anti-windup compensator to AQM in TCP/IP networks

Abstract

In this paper, input delay theory is used as a key tool to design an effective anti-windup compensator which is applied to active queue management (AQM) at router to avoid congestion. The desired anti-windup compensator can be computed by the solution of convex optimization problem. The simulation results suggest that our methodology is effective and is an improvement over previous ones.
