Brief paper: Interconnection topologies for multi-agent coordination under leader-follower framework
TL;DR: It is shown that the controllability of a multi-agent system can be uniquely determined by the topology structure of interconnection graph, for which the investigation comes down to that for a multi -agent system with the interconnectiongraph being connected.
Journal ArticleDOI
A New Perspective to Graphical Characterization of Multiagent Controllability
Zhijian Ji,Haisheng Yu +1 more
TL;DR: The concept of controllability destructive nodes is proposed, which indicates that the difficulty in graphical characterization turns out to be the identification of topology structures of controlla destructive nodes.
Journal ArticleDOI
Protocols design and uncontrollable topologies construction for multi-agent networks
Zhijian Ji,Hai Lin,Haisheng Yu +2 more
TL;DR: A neighbor-based control protocol is proposed, under which it is shown that the controllability of a multi-agent system is solely decided by its communication topology structure.
Journal ArticleDOI
Leaders in multi-agent controllability under consensus algorithm and tree topology
Zhijian Ji,Hai Lin,Haisheng Yu +2 more
TL;DR: The main objective of this paper aims to characterize the virtue that leaders should have from the perspective of algebraic and graphical conditions and shows for path topologies that controllability completely depends on the leaders’ location.
Journal ArticleDOI
Controllability of multi-agent systems based on agreement protocols
TL;DR: It is proved that, under the same topology and same prescribed leaders, a network of high-order dynamic agents is completely controllable if and only if so is anetwork of single-integrator agents.
