In this paper, we address the problem of distributed leader selection in a network of agents. We assume that each agent's state is defined by a scalar that evolves according to a linear dynamics involving the states of its neighbors and its own state. We propose a distributed algorithm, assuming a time-invariant communication graph, to determine: (i) those agents that should behave as leaders (i.e...
This paper explores the role of symmetry when establishing output controllability and stabilizability of LTI networked systems. Previous work, which examined graph symmetry through its signed fractional graph automorphisms, has been extended to output controllability and stabilizability. Conditions on input symmetry, output symmetry, and non-output symmetry over the network are proved to provide necessary...
