The attacks on power systems have been happening all the time, and gradually changing from a single attack to hybrid multiple cyber attacks. Such may cause more catastrophic damages security safety of multi-area systems. Here, control problem is analyzed for under Two Lyapunov–Krasovskii functionals are constructed, by utilizing second-order canonical Bessel–Legendre inequality, sufficient cond...

We investigate the local exponential synchronization for complex dynamical networks with interval time-varying delays in the dynamical nodes and the switched coupling term simultaneously. The constraint on the derivative of the time-varying delay is not required which allows the time delay to be a fast time-varying function. By using common unitary matrix for different subnetworks, the problem ...

An adaptive iterative learning control scheme is presented for a class of strict-feedback nonlinear time-delay systems, with unknown nonlinearly parameterised and time-varying disturbed functions of known periods. Radial basis function neural network and Fourier series expansion (FSE) are combined into a new function approximator to model each suitable disturbed function in systems. The require...

This paper is concerned with the problem of adaptive fuzzy output tracking for a class of perturbed strict-feedback nonlinear systems with time delays and unknown virtual control coefficients. Fuzzy logic systems in Mamdani type are used to approximate the unknown nonlinear functions, then the adaptive fuzzy tracking controller is designed by using the backstepping technique and Lyapunov–Krasov...

This paper investigates the H∞ state estimation problem for gene regulatory networks (GRNs) with timevarying delays and Markovian jumping parameters. The system output, which is used by the estimator, is assumed to be sampled and held during a sampling period. To deal with the time-varying delays, each delay function is limited to certain lower and upper bounds. By using Lyapunov-Krasovskii fun...

The formation control problem of a team of Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicles (UAVs) with communication delays is addressed. Based on the extraction algorithm presented in Abdessameud and Tayebi (2010a), we propose a new design methodology that simplifies the design of formation control laws with delayed communication for this class of under-actuated systems. Three co...

The problems on global dissipativity and global exponential dissipativity are investigated for uncertain discrete-time neural networks with time-varying delays and general activation functions. By constructing appropriate Lyapunov-Krasovskii functionals and employing linear matrix inequality technique, several new delay-dependent criteria for checking the global dissipativity and global exponen...

The construction of Lyapunov–Krasovskii functionals with prescribed time derivative in the framework of the stability analysis of time delay systems has been addressed in several works, starting with the contributions of Repin (1965) and Datko (1971). In the past decade, this topic has been revisited by Kharitonov and Zhabko (2003), with the so-called functionals of complete type whose time der...
