| Abstract: | Robust fault-tolerant control is presented for a class of uncertain time-delay large-scale systems in this paper.The robust fault-tolerant Control for sensor or actuator are studied.At first,a delay-dependent stability criterion for time-delay large-scale systems without perturbations is obtained through a new method based on integral quadratic constraints（IQC） performance,linear matrix inequality（LMI） and Lyapunov function.Next,a criterion for uncertain time-delay large-scale systems is obtained via derivations.At the same time,Robust fault-tolerant controller is designed. |
