Abstract

In this paper a new sliding mode flow controller for multi-source connection-oriented communication networks is proposed. The networks are modeled as discrete time, n-th order systems. On the basis of the system state space description, a novel sliding mode controller with linear quadratic (LQ) optimal switching plane is designed. The control law derivation concentrates on the minimization of LQ cost functional and solving the resultant matrix Riccati equation. Closed loop system stability is demonstrated, and conditions for no data loss and full bottleneck link bandwidth utilization in the network are presented, and strictly proved.
