Abstract: Aimed at the situation lacking of realization system platform for real-time distributed multi-agent control theory, a new proposition for fieldbus control system acting as a generic system platform to realize real-time distributed multi-agent control theory is proposed in this paper. With the analysis of the proliferation reasons, architecture, and characteristics of fieldbus control, the proposition is proven to be correct and feasible. A strategy on how to meet the various fieldbuses'challenge is also given. The proposition points out a new way for the control theory research of realtime distributed multi-agent to step out of dilemma and make a new breakthrough.
