This paper considers the problem of designing a non-fragile fault-tolerant controller for a class of nonlinear uncertain systems with time-varying delays and controller gain perturbations. Based on the Lyapunov stability theory and the linear matrix inequality (LMI) approach, a sufficient conditions to get a fault-tolerant controller is given, which results in the closed-loop system being asymptotically...
The problem of H∞ guaranteed cost control for delay-dependent stochastic systems is considered. Both distributed delays and delay dependent appear in the systems. A delay-dependent stabilization condition is given in terms of Lyapunov stability theory and the linear matrix inequality (LMI) technique. Furthermore, a sufficient condition of the existence of H∞ guaranteed cost controller is constructed...
This paper addresses the problem of robust L2-L∞ Filtering for a class of nonlinear uncertain stochastic time delay systems. Attention is focused on the design of a stochastic L2-L∞ filter that ensuring both the asymptotic mean-square stability and a prescribed L2-L∞ performance level of the filtering error system. A full-order filter is designed based on the linear matrix inequality. Sufficient conditions...
In this study, a novel fault-tolerant control scheme is proposed for a class of T-S fuzzy time-delays systems with sensor faults based on fuzzy descriptor system approach. The control strategy takes the form of parallel distributed compensation. Letting the sensor fault term to be an auxiliary state vector, an augmented fuzzy descriptor model is constructed. Then, a novel fuzzy observer is designed...
