Distributed cooperative control of nonlinear and non-identical multi-agent systems

This paper exploits input-output feedback linearization technique to implement distributed cooperative control of multi-agent systems with nonlinear and non-identical dynamics. Feedback linearization transforms the synchronization problem for a nonlinear and heterogeneous multi-agent system to the synchronization problem for an identical linear multiagent system. The controller for each agent is designed to be fully distributed, such that each agent only requires its own information and the information of its neighbors. The proposed control method is exploited to implement the secondary voltage control for electric power microgrids. The effectiveness of the proposed control is verified by simulating a microgrid test system.
