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

Consensus of second-order heterogeneous multi-agent systems under a directed graph
TL;DR: An adaptive σ-modification scheme for the gain adaption is proposed, which renders smaller control gains and thus requires smaller amplitude on the control input without sacrificing the consensus convergence.

Group consensus control for networked multi-agent systems with communication delays.
TL;DR: This paper investigates group consensus problems in networked multi-agent systems (NMAS) with communication delays based on the sed state prediction scheme and finds necessary and sufficient conditions of group consensus with respect to a given admissible control set are obtained for the NMAS with communication delay under mild assumptions.

Adaptive synchronization of unknown heterogeneous agents: An adaptive virtual model reference approach
Simone Baldi,Paolo Frasca +1 more
TL;DR: A Lyapunov-based approach is derived to show analytically asymptotic convergence of the synchronization error: robustification in the presence of bounded errors or unknown (constant) leader input is also discussed.

Fully Distributed Low-Complexity Control for Nonlinear Strict-Feedback Multiagent Systems With Unknown Dead-Zone Inputs
Gang Wang,Chaoli Wang,Lin Li +2 more
TL;DR: A control algorithm is proposed to ensure predefined bounds of overshoot, convergence rates, and steady-state values of the neighborhood synchronization errors in the presence of unknown dead-zone inputs.

Consensus in the network with uniform constant communication delay
TL;DR: An achievable upper bound of delay tolerance is obtained which explicitly depends on agent dynamics and network topology and is proposed so that the multi-agent consensus in a set of unknown networks can be achieved.

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.
