Linear Quadratic Optimal Flow Control in Multi-Source Connection-Oriented Communication Networks
Przemysław Ignaciuk, Andrzej Bartoszewicz · 2008
In this paper control theoretic approach is applied to design a new, optimal flow controller for multi-source connection-oriented communication networks. The networks are modeled as discrete time, n-th order systems. On the basis of the system state space description, a feedback control law is derived by minimizing linear quadratic (LQ) cost functional. 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.
