Robust Reliable Control for Uncertain Nonlinear Systems With Time-Delay

In this paper, the robust reliable control is investigated for a class of uncertain nonlinear system with time-delay. The system under consideration involves state time delay, control input time delay, parameter uncertainties and unknown nonlinear disturbances. The purpose of this paper is to design a memoryless state feedback linear controller such that, for all admissible uncertainties and any actuator failure occurring in 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. The simulation shows that the method is very effective.
