Mode-Dependent Scalable Control for Large-Scale Networked Systems

A novel mode-dependent scalable control strategy is proposed for large-scale networked systems, which are composed of several dynamically interconnected subsystems. First, to remove the restrictions on the coupling structure of these subsystems, an arbitrary topology is carefully constructed. Then, some sufficient conditions under the subsystem level are derived, which uses each subsystem's knowledge of its own dynamics and a limited amount of information about the coupled subsystems. Moreover, a set of flexible controller gains are solved, guaranteeing all closed-loop signals to be globally exponentially stable. Finally, simulation results on a coupled microgrid validate the effectiveness of the proposed approach.
