H∞ consensus is investigated for multi-agent systems with linear dynamics and impulsive effects in this paper. First of all, by considering the effects of distributed impulses, the model of linear multi-agent systems with impulsive effects and external disturbances has been obtained. Then, in view of the average impulsive interval and the Lyapunov stability theory, an algorithm has been given to solve...
This paper is concerned with pth moment exponential stability of stochastic delayed neural networks. By using the Lyapunov function method, some stability criteria of impulsive stochastic delayed systems are obtained, and these results are applied to the study on the stability criteria of stochastic delayed neural networks. It is shown that if the continuous stochastic delayed neural network is stable...
In this paper, consensus of multi-agent systems containing linear self dynamics is investigated. By considering packet losses, a sampled data protocol with packet losses is considered. A switched systems including stable modes and unstable modes is considered here to describe packet losses. By using the contradiction method and the Lyapunov function method, a sufficient condition on consensus of the...
In order to improve the static and dynamic responses of three-phase grid-connected inverter systems, this paper proposes a composite control consisting of a PI control and a repetitive control. This method can be used to reject the periodic harmonic signals, and thus improve the converter output performance. A high-order repetitive controller is adopted to further improve the robustness against the...
This paper investigates the distributed containment control of multi-agent systems with multiple stationary leaders with event-triggering protocols. A distributed event-triggering protocol is proposed, where the triggering function of each agent with an exponentially decreasing threshold is developed to guarantee the convergence of the followers to the convex hull formed by the leaders. Finally, simulations...
As one of the key factors, the relationships of expansion volume and arcing characteristics have been treated importantly for the design and optimization of gas circuit breakers. In the paper, a simple 145kV auto-expansion circuit breaker model is adopted. With the method of MHD, arcing process under three different expansion volumes at large current 60Hz interruption is simulated. The contours of...
In this paper, the synchronization problem is studied for complex networks under impulsive control with packet loss. At some impulsive instant, if the control packet from the controller to the actuator is lost, then we assume that the impulsive strength is zero. By using the comparison principle, a sufficient condition is derived to guarantee that exponential synchronization of complex networks is...
By improving of the dielectric performance between the breakers, medium condition and arc extinguishing ability, the breaking capacity of circuit breaker is increased. The main architecture of the 252kV circuit breaker is determined in which double chamber of interrupter construction + dual-direction moving of contacts mode are introduced. The key structure design parameter have been optimized combined...
In this paper, the robust stability problem of genetic regulatory networks (GRNs) with mixed delays is investigated. By choosing an appropriate Lyapunov-functional, some mixed time delays dependent stability criteria for GRNs are derived in the form of linear matrix inequalities (LMI), which can be easily checked by Matlab Toolbox. Both the lower bounds and upper bounds of discrete and distributed...
Previous works on network coding capacity for wireless networks have taken the assumption that the network is stationary. In this paper, the mobility of ad hoc networks is considered as a key factor influencing network capacity, and a new and unified analytical expression of the capacity of a mobile ad hoc network applying network coding is derived under the two main mobility models, including random...
