On the stability of AQM controllers supporting TCP flows
Melchor Aguilar, Daniel Alejandro
"In this chapter we address the local asymptotic stability of some AQM controllers supporting TCP flows. We first consider a PI controller as AQM strategy. The complete set of PI controllers that stabilizes the linearized closed-loop system is obtained. Then, we consider a delay-dependent AQM controller based on control laws for finite spectrum assignment of time-delay systems. Stability conditions for a numerically safe implementation of the controllers are provided."
