Robust reliable control for uncertain nonlinear systems with time-varying delay

The problem of robust reliable control is investigated for a class of uncertain nonlinear system with time-varying delay. The system under consideration involves state time delay, input time delay, parameter uncertainties and unknown nonlinear disturbances. The purpose of this paper is to design the memoryless state feedback linear 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.
