Passivity-based output synchronization of interconnected linear systems

This paper deals with output synchronization of linear interconnected system with general interconnection. The main result is that output synchronization of the interconnected system can be achieved through the consensus algorithm if passivity of the system is satisfied. Furthermore, the analysis is released in decentralized way, and we design observer-based state feedback controller. The following controller and observer gains can be calculated from LMI conditions in the decentralized scheme. Two simulations and conducted to evaluate the validity of the synchronization analysis and effectiveness of design of the control law.
