TLDR
It is shown that information consensus under dynamically changing interaction topologies can be achieved asymptotically if the union of the directed interaction graphs have a spanning tree frequently enough as the system evolves.Abstract:
This note considers the problem of information consensus among multiple agents in the presence of limited and unreliable information exchange with dynamically changing interaction topologies. Both discrete and continuous update schemes are proposed for information consensus. This note shows that information consensus under dynamically changing interaction topologies can be achieved asymptotically if the union of the directed interaction graphs have a spanning tree frequently enough as the system evolves.read more

Multi-vehicle coordination for double-integrator dynamics under fixed undirected/directed interaction in a sampled-data setting
Yongcan Cao,Wei Ren +1 more
TL;DR: In this article, the convergence of two coordination algorithms for double-integrator dynamics under fixed undirected/directed interaction in a sampled-data setting is studied, and necessary and sufficient conditions on the sampling period, the control gain, and the communication graph are presented.

Decentralized Multi-Agent System-Based Cooperative Frequency Control for Autonomous Microgrids With Communication Constraints
TL;DR: Based on power line carrier communication technology, a decentralized multi-agent system (DMAS)-based frequency control strategy is proposed and investigated in this paper on an autonomous microgrid with communication constraints, where each agent can only communicate with its neighboring agents.

Conditions for Synchronizability in Arrays of Coupled Linear Systems
TL;DR: In this article, the authors studied synchronization in arrays of coupled continuous-time linear systems and showed that for neutrally stable systems that are detectable from their outputs, a linear feedback law exists under which any number of coupled systems synchronize provided that the (directed, weighted) graph describing the interconnection is fixed and connected.

Distributed adaptive asymptotically consensus tracking control of nonlinear multi-agent systems with unknown parameters and uncertain disturbances
TL;DR: This paper investigates distributed adaptive consensus tracking control without such requirements for nonlinear high-order multi-agent systems subjected to mismatched unknown parameters and uncertain external disturbances by introducing compensating terms in a smooth function form of consensus errors and certain positive integrable functions in each step of virtual control design.

Consensus problems in networks of agents with switching topology and time-delays
TL;DR: A distinctive feature of this work is to address consensus problems for networks with directed information flow by establishing a direct connection between the algebraic connectivity of the network and the performance of a linear consensus protocol.

TL;DR: A theoretical explanation for the observed behavior of the Vicsek model, which proves to be a graphic example of a switched linear system which is stable, but for which there does not exist a common quadratic Lyapunov function.
