This paper investigates the problem of fault tolerant control of a class of uncertain switched nonlinear systems with time delay under asynchronous switching. The systems under consideration suffer from delayed switchings of the controller. First, a fault tolerant controller is proposed to guarantee exponentially stability of the switched systems with time(More)
The problem of robust H∞ reliable control for a class of uncertain stochastic switched non-linear systems is investigated in this paper. The parameter uncertainties are assumed to be time-varying but norm-bounded. Firstly, using the average dwell time approach, a criterion of mean-square exponential stability with H∞ performance for stochastic non-linear(More)
This paper is concerned with the problem of controller design for switched systems under asynchronous switching with exogenous disturbances. The attention is focused on designing the feedback controller that guarantees the finite-time bounded and L∞ finite-time stability of the dynamic system. Firstly, when there exists asynchronous switching between the(More)
This paper investigates the problem of the nonfragile observer design for discrete-time switched nonlinear systems with time delay. Based on the average dwell-time approach and linear matrix inequality (LMI) techniques, an exponential stability criterion for the discrete-time switched delay system with Lipschitz nonlinearity is derived. Based on several(More)
This paper considers the problem of stability and robust stabilization for a class of uncertain time delay switched systems using the delta operator. Based on multiple Lyapunov-Krasovskii function in delta domain, a sufficient condition for the existence of stability of the delta operator time delay switched system is presented, and a new sampling period(More)
