The problem of robust decentralized reliable control is investigated for a class of uncertain interconnected system with time-delay. The system under consideration involves state time delay and parameter uncertainties. The purpose is to design the decentralized observer and linear memoryless dynamic output feedback controller such that, for all admissible uncertainties as well as actuator failures occurring among a prespecified subset of actuators, the closed-loop system is asymptotically stable. Finally, a numerical example is presented to illustrate the results given in this paper and simulation shows that the method is very effective.
