This paper deals with the problem of delay-dependent robust H∞ control for discrete-time recurrent neural networks (DRNNs) with norm-bounded parameter uncertainties and interval time-varying delay. The activation functions are assumed to be globally Lipschitz continuous. For the robust stabilization problem, a state feedback controller is designed to ensure global robust stability of the closed...

This paper investigates the problem of observer design for a class of nonlinear systems with timedelay and uncertain nonlinearity. Firstly, using the Mean-value Theorem and combining constructing the Lyapunov-Krasovskii functional, the convergence conditions of nonlinear observer for a class of nonlinear systems with time-varying delay and uncertain nonlinearity are established in terms of a li...

The problem of robust stability analysis for uncertain discrete singular time-delay systems is investigated in this paper. By decomposing the nominal system into slow and fast subsystems, a linear matrix inequality (LMI) condition is proposed for a discrete singular time-delay system to be regular, causal and stable. Based on this, an LMI criterion is obtained for robust stability of an uncerta...

The H , control problem for uncertain descriptor systems with time-invariant normbound uncertainty in the state matrix is considered. Necessary and sufficient conditions for robust H, control of descriptor systems by state feedback and dynamic output feedback are derived. The design results are expressed in terms of generalised algebraic Riccati inequalities, which may be considered an extensio...

In this paper, global robust stability of stochastic impulsive recurrent neural networks with time-varyingdelays which are represented by the Takagi-Sugeno (T-S) fuzzy models is considered. A novel Linear Matrix Inequality (LMI)-based stability criterion is obtained by using Lyapunov functional theory to guarantee the asymptotic stability of uncertain fuzzy stochastic impulsive recurrent neural...

This paper discusses robust H∞ disturbance attenuation of uncertain discrete-time systems that have time-varying delay in state. There have been only a few results on H∞ disturbance attenuation for discrete-time delay systems. Especially, few results on robust H∞ disturbance attenuation for a class of uncertain discrete-time delay systems have appeared in the literature. Therefore, the study of...

In this paper, we characterize the achievable input performance for linear time invariant systems under feedback control. We provide analytical expressions for minimal input requirement for stabilization in both of the H2 and H∞ optimal control frameworks. The achievable input performance primarily depends on the joint controllability and observability of unstable poles. These results are also ...

In this paper, we characterize the achievable input performance for linear time invariant systems under feedback control. We provide analytical expressions for minimal input requirement for stabilization in both of the H2 and H1 optimal control frameworks. The achievable input performance primarily depends on the joint controllability and observability of unstable poles. These results are also ...
