Decentralized H∞ control for linear interconnected large-scale systems with time delay

ABSTRACT This paper examines the decentralized control problem for linear interconnected large-scale systems with time delay. The problems of decentralized stabilization and decentralized H ∞ performance are concerned based on the standard H∞ control theory. Both decentralized static state feedback control and linear dynamic output feedback control laws are investigated in terms of linear matrix inequalities.
