In this note, the problem of second-order leader-following consensus by a novel distributed event-triggered sampling scheme in which agents exchange information via limited communication medium is studied. Event-based rules are designed, where each agent decides when to measure its own state value and requests neighbor broadcast their values across network locally-computed measurement error exceeds state-dependent threshold. For case fixed topology, necessary sufficient condition...

The event-based control strategy is an effective methodology for tackling the distributed of multi-agent systems with limited on-board resources. This technical note focuses on leader-following consensus described by general linear models and subject to input time delay between controller actuator. For each agent, updates are only triggered at its own event times. A necessary condition two sufficient conditions presented, respectively. It shown that continuous communication neighboring...

This paper investigates exponential stabilization of continuous-time dynamic systems (CDSs) via event-based impulsive control (EIC) approaches, where the instants are determined by certain state-dependent triggering condition. The global stability criteria EIC derived for nonlinear and linear CDSs, respectively. It is also shown that there no Zeno-behavior concerned closed loop system. In addition, developed scheme applied to synchronization problem master slave memristive neural networks....

In this paper, we consider the event-triggered distributed average-consensus of discrete-time first-order multiagent systems with limited communication data rate and general directed network topology. framework digital network, each agent has a real-valued state but can only exchange finite-bit binary symbolic sequence its neighborhood agents at time step due to channels energy constraints. Novel dynamic encoder decoder for are designed, based on which control algorithm is proposed. A scheme...

This paper discusses the second-order local consensus problem for multi-agent systems with nonlinear dynamics over dynamically switching random directed networks. By applying orthogonal decomposition method, state vector of resulted error dynamical system can be decomposed as two transversal components, one which evolves along manifold and other transversally manifold. Several sufficient conditions reaching almost surely are derived cases time-delay-free coupling time-delay coupling,...

Video watching time is a crucial measure for studying user behavior in online Internet video-on-demand (VoD) systems. It important system planning, engagement understanding, and quality evaluation. However, due to the limited access of data large-scale streaming systems, systematic measurement, analysis, modeling video still missing. In this paper, we PPLive, one most popular commercial VoD systems China, over three week period. We collect accurate more than 100 million sessions thousand...

Event-triggered formation control of multiagent systems under an undirected communication graph is investigated using complex-valued Laplacian. Both continuous-time and discrete-time models are considered. The dynamics each agent described by differential or difference equations. For agent, only the information its neighbors used in design controllers event triggers. Triggering time instants for any determined certain events that depend on states neighboring agents. Continuous updating...

Event-triggered formation control of linear continuous-time multiagent systems is studied in this article. A complex-valued Laplacian adopted by the local information desired formation. For each agent, an event-triggering mechanism based on neighboring at time instants presented and continuous communications between agents are avoided. Furthermore, event-triggered strategy using idea dynamic state observer designed. It shown that any shape can be achieved. Moreover, Zeno-behavior strictly...
