This paper examines the controllability of a group of first order agents, adopting a weighted
consensus-type coordination protocol over a circulant network. Specifically, it is shown that a
circulant network with Laplacian eigenvalues of maximum algebraic multiplicity q is
controllable from q nodes. Our approach leverages on the Cauchy–Binet formula, which in
conjunction with the Popov–Belevitch–Hautus test, leads to new insights on structural
aspects of network controllability.
