Abstract : In this study, the distributed control strategy is proposed for the automatic gauge control(AGC) system, which is a typical multi-agent system. The distributed control protocol is developed with the subspace identification method using the measurements of the local agent and its neighbors directly,without any knowledge of the AGC system dynamics. The stability analysis of the multi-agent system with the proposed control protocol is given. In addition, the consensus control protocol with communication time delay is investigated. Finally, simulation results are carried out to verify the feasibility and effectiveness of the proposed control strategy.

Keyword : Automatic gauge control, distributed control, multi-agent, subspace identification.
