Description
Summary:This article studies leaderless output sign consensus of heterogeneous multi‐agent systems over directed signed graphs. The multi‐agent system can synchronize in the same sign concurrently with time‐varying values without an explicit leadership. Established on the assumption that the adjacency matrix of the signed graph is eventually positive, an autonomous system is constructed by utilizing a distributed sign observer. This autonomous system is not pre‐specified but arises from the graph topology and the initial states of the agents. In light of this distributed sign observer, we propose a state feedback controller and an output feedback controller that drive the outputs of such multi‐agent systems to reach sign consensus.
