The problem of passivity is discussed in this paper for reaction-diffusion Cohen-Grossberg neural networks (CGNNs) with multiple time-varying delays. By constructing suitable lyapunov functionals and employing some inequality techniques, several sufficient conditions guaranteeing the passivity of CGNNs are obtained. Furthermore, several criteria for robust passivity are also derived for the case that...
This note is concerned with stability analysis of integral delay systems with multiple delays. To study this problem, the well-known Jensen inequality is generalized to the case of multiple terms by introducing an individual slack weighting matrix for each term, which can be optimized to reduce the conservatism. With the help of the multiple Jensen inequalities and by developing a novel linearizing...
This paper considers the problem of delay-dependent robust H-infinity control of time-delay switched systems with disturbance and time-varying structured uncertainties. On the basis of the Lyapunov function and linear matrix inequality approach, we obtain the sufficient conditions for H-infinity robust stabilization of the uncertain time-delay switched systems under arbitrary switching signals. By...
This paper proposes a dynamic model of a closed-loop supply chain system with remanufacturing delay and disposal delay. A mixed algorithm combining immune genetic algorithm and linear matrix inequality method is designed for achieving the globally optimal performance of H∞ control for the closed-loop supply chain system. The study shows that the globally optimal performance of the system deteriorates...
This paper presents a preliminary result for the problem of robust Hinfin control for linear uncertain switched systems with time-varying delay. Based on multi-Lyapunov function method and linear matrix inequality method, a sufficient condition for switched systems with robust stability and Hinfin criteria gamma using a state-based switching law is proposed.
A class of uncertain systems with time-varying input-delays are modeled by fuzzy T-S model. A new controller design is developed on the basis of the fuzzy modeling, and on the Lyapunov-Razumikhin stability theorem, give a sufficient condition for the asymptotic stability of the T-S fuzzy systems and the method of designing the controller
