Network Realization Functions for Optimal Distributed Control

In this article, we discuss a distributed control architecture, aimed at networks with linear and time-invariant dynamics, which is amenable to convex formulations for controller design. The proposed approach is well suited for large-scale systems, since the resulting feedback schemes completely avoid the exchange of internal states, i.e., plant or controller states, among subcontrollers. In addition, we provide state-space formulas for these subcontrollers, able to be implemented in a distributed manner.
