Abstract : this paper considers the decentralized stabilization problem via local state feedback control laws for a class of large - scale linear discrete - time systems with delay interconnections. a sufficient condition for decentralized stabilizability is derived and is expressed as a system of linear matrix inequalities. furthermore, the problem of designing a decentralized state feedback control law with smaller feedback gain parameters is formulated as a convex optimization problem, and latter can be solved by using existing efficient convex optimization techniques. the obtained controller enables the closed - loop systems to be not only stable, but also of any prescribed stability degree
