Robust fault-tolerant control of systems with time-varying structured uncertainties

Robust fault-tolerant control for uncertain systems with time-varying delays is considered in the paper. Basing on the Lyapunov stability theory and the linear matrix inequality (LMI) method, the sufficient condition for the sensor fault system to have robust stabilization and robust fault-tolerant capability is derived. In view of the different fault types, a multi-state fault model is presented. The state feedback controller with perturbation terms is calculated. A numerical example and its simulation results are given to illustrate the effectiveness of the approach.
