In this paper, structural controllability of a leader–follower multi-agent system with multiple leaders is studied from a graph-theoretic point of view. The problem of preservation of structural controllability under simultaneous failures in both the communication links and the agents is investigated. The effects of the loss of agents and communication links on the controllability of an information...
The detectability of single link failures in a multi-agent network under the agreement protocol has been the subject of a previous study. This work expands the available results by considering the effect of multiple link losses. The analytical results offer sufficient graphical conditions for the detectability of a group of edges in the network information flow digraph. To this end, a powerful extension...
The concept of detectability for a link with respect to an agent in a multi-agent system is introduced in this work. Link failures in the network are characterized in terms of their detectability, depending on how a link failure affects the response of a particular node in the system, and whether the link failure can be determined by observing that node's response. Sufficient conditions for detectability...
