Abstract :
In this note, the problem of robust reliable control for a class of linear neutral delay-differential system with actuator failures is investigated. The neutral system contains state time delay, input time delay and parameter uncertainties. We introduce the parameterized model transformation method and the free-weighting-matrix method to obtain the delay-dependent reliable stability results against actuator failures. The memoryless state feedback linear controller is designed so that for all admissible uncertainties as well as actuator failures occurring among a prespecified subset of actuators, the closed-loop system is asymptotically stable. Moreover, less bounding for cross terms is used to decline the conservatism. Finally, a numerical example is given to illustrate the effectiveness of the proposed criteria
