- Abstract:
-
The relationship between the controllability of network topology and individual dynamics in the overall controllability of the system is studied, and a new model describing the general linear multi-agent system is proposed. Using the Popov-Belevitch-Hautus (PBH) criterion, the necessary and sufficient conditions for the controllability of a multi-agent system in the network topology and individual dynamic level are obtained and proved, and the effect of repeated eigenvalues in the system matrix on the sufficiency of Theorem 2 is explained with a concrete example. We provide a way to avoid the occurrence of repeated eigenvalues. In particular, the two conditions for judging the uncontrollable system can be determined when the system matrix is a real symmetric matrix under this model; that is, compare the largest eigenvalue algebraic multiplicity in the system matrix with the number of 1 elements in the control matrix. If this condition is satisfied, the system is uncontrollable.
