Abstract: Non-fragile fault-tolerant controller is designed for a class of linear uncertain time-delayed systems. Two cases of controller perturbation are investigated in view of different application conditions. One case is the controller gain attenuation, the other is random uncertainty caused by noise possibly existing in an industrial field. The controller to be designed can guarantee systems to have robust fault-tolerant capability and non-fragility. Sufficient conditions for the existence of such controllers are derived basing on Lyapunov stability theory and LMI method. A numerical example of a beam reheating furnace is given. And computation results demonstrate the effectiveness of the proposed algorithm.
