Adaptive coordinated decentralized control of state delayed systems with actuator failures

This paper develops an adaptive state feedback coordinated decentralized control scheme for a class of dynamic systems with state delay in subsystems and in the interconnections and in the presence of unknown actuator failures in each subsystem. The main contributions of this paper are the development of a new controller parametrization which attempt to anticipate the future states and failures, the introduction of an appropriate Lyapunov-Krasovskii type functional to design the adaptation algorithms, and a stability proof.
