Abstract :
In this paper, we investigate the effect of insufficient time-scale separation between inner and the outer loops in a cascaded, networked system under multiple clients. Inspired by the AQM (inner loop) and TCP (outer loop) at the Internet transport layer, a qualitative model is developed where the stability of the cascaded system is analyzed in terms of the gains acting at the outer and inner loops.
