In networked load frequency control (LFC) systems, time-varying delays could come from two aspects: measurements' transmission from power plant to control center and control signals from the control center to plant side, because of the use of open communication networks. Those delays can affect the dynamic performance and the stability of the system. In this paper, the two delays are considered in...
There is an ever-increasing interest in studying temporal networks nowadays, as temporal networks can illustrate the real-world system more accurately. To date, how to characterize nodes' importance is still unclear in temporal networks. In this work, we first use a time window graph model to cut the temporal network into slices, and then we give an indicator for network centrality according to the...
This paper investigates the problem of stability analysis of neural networks with time-varying delay. Some augmented double integral term and triple integral terms are introduced to the Lyapunov-Krasovskii functional (LKF). And the derivative of the LKF is estimated by the free-matrix-based integral inequality. Then, a less conservative stability criterion is derived. Finally, a numerical example...
This paper investigates the exponential stability for neural networks with time-varying delay based onWirtinger-based inequality. Firstly, a simple Lyapunov-Krasovskii functional (LKF) containing a triple integral term is constructed. Then, the treatment to the derivation of the triple integral term leads to a great effect combining withWirtinger-based inequality. As a result, an improved delay-dependent...
This paper studies stability of solutions for a class of stochastic impulsive systems. The impulsive stochastic comparison theorem is established using stochastic differential inequalities. By using the comparison theorem, the comparison criterion of asymptotic stability of trivial solution of the systems is obtained based on vector Lyapunov-like function.
