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)
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 non-linearity is derived. Based on several(More)
—This paper considers the non-fragile observer design method for nonlinear switched time delay systems using the delta operator. Based on multiple Lyapunov function method and delta operator theory, an asymptotic stability criterion for delta operator switched system with time delay and Lipschitz nonlinearity is presented. By using the key technical lemma,(More)
