Decentralized pole placement controller design for networks of linear systems

A broad class of networks of linear control systems is characterized by a unit time delay in communication between neighboring systems. Whenever the local systems are structurally controllable and observable, a generic decentralized dynamic feedback law ensures that each strongly connected component of such a network is structurally controllable and observable from any local plant-controller pair within the component. This leads to a simple pole placement design procedure that ensures generic, arbitrary assignability of the closed-loop system eigenvalues via decentralized dynamic feedback control regardless of the communication topology.
