【Abstract】 Based on Lyapunov stability theory,a class of problems concerning non-fragile guaranteed cost fault tolerant control with disturbance attenuation for uncertain nonlinear discrete-time systems with delay is studied.Considering the actuator failure and additive perturbation about parameters of the controller,existing conditions and the design method of non-fragile guaranteed cost fault tolerant controller are given,and a neat expression of controller is deduced consequently with the LMI.A numerical example is used to illustrate the effectiveness of the presented method.No-fragile guaranteed cost fault tolerant control with disturbance attenuation for uncertain nonlinear discrete-time systems with delay更多还原
