摘      要：In this paper, the global sampled-data control problem has been considered for large-scale switched time-delay nonlinear systems subject to actuator failures. A reduced-order observer is developed to estimate unmeasured states, and a decentralized sampled-data controller is designed with an allowable sampling period. It can be shown that all states of the corresponding closed-loop system are globally uniformly ultimately bounded under arbitrary switchings through the choice of the suitable Lyapunov- Krasoviskii functional. Finally, the validity of the proposed control scheme is verified using an example.
