Centrality in time-delay consensus networks with structured uncertainties

Novel stability criterion of time delay systems with nonlinear uncertainties

In this paper, a class of time delay systems with nonlinear uncertainties is considered. A novel robust stability criterion of the system is derived by using the Lyapunov method. The criterion can be easily solved by efficient convex optimization algorithms. Two numerical examples are given to illustrate the superiority of our result to those in the literature. © 2004 Elsevier Ltd. All rights r...

Robust stabilisation of time-varying delay systems with probabilistic uncertainties

For robust stabilisation of time-varying delay systems, only sufficient conditions are available to date. A natural question is as follows: if the existing sufficient conditions are not satisfied, and hence no controllers can be found, what can one do to improve the stability performance of time-varying delay systems? This question is addressed in this paper when there is a probabilistic struct...

Time Centrality in Dynamic Complex Networks

There is an ever-increasing interest in investigating dynamics in timevarying graphs (TVGs). Nevertheless, so far, the notion of centrality in TVG scenarios usually refers to metrics that assess the relative importance of nodes along the temporal evolution of the dynamic complex network. For some TVG scenarios, however, more important than identifying the central nodes under a given node centra...

Finite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay

In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...
