Abstract:This paper investigates the herdability of multi-agent systems with general linear and signed matrix-weighted networks under signed directed graphs. Firstly, we present the sufficient conditions for herdability of general linear multi-agent systems by utilizing controllability structure decomposition. Moreover, leveraging the concepts of controllable subspaces and graph theory, we propose a set of graph-theoretic conditions for the herdability of multi-agent systems under different matrix weight scenarios. Finally, we introduce the definition of signed matrix-weighted distance-equivalent partitioning and provide the herdability criteria for general matrix-weighted networks under this partitioning. It is found that the system is herdable when the non-zero elements of the weight matrix are either all positive or all negative.
