- Abstract:
-
The controllability of complex networks is analyzed in the paper for path topology. With adjacency matrix of the system being decomposed into submatrices, the relationship between eigenvalues and eigenvectors is revealed for the partitioned submatrices. Furthermore, necessary and sufficient conditions are derived by taking advantage of the PBH(Popov-Belevitch-Hautus) criteria. In particular, a method is proposed to determine path controllability when the controlled nodes are any single or multiple nodes, as well as the concept of uncontrollable eigenvalues is presented. The expressions for uncontrollable eigenvalues are provided as well. Two theorems in this paper is verified by examples and the results of examples are in agreement with the conclusion of the theorems.
