Abstract EN
The concept of controllability from control theory is applied to weighted and directed networks with heterogenous linear or linearized node dynamics subject to exogenous inputs, where the nodes are grouped into leaders and followers.
Under this framework, the controllability of the controlled network can be decomposed into two independent problems: the controllability of the isolated leader subsystem and the controllability of the extended follower subsystem.
Some necessary and/or sufficient conditions for the controllability of the leader-follower network are derived based on matrix theory and graph theory.
In particular, it is shown that a single-leader network is controllable if it is a directed path or cycle, but it is uncontrollable for a complete digraph or a star digraph in general.
Furthermore, some approaches to improving the controllability of a heterogenous network are presented.
Some simulation examples are given for illustration and verification.
