A Research on the Open MAS Cooperative Control Mechanism based on Multi-Fieldbus Environment

Analysis thinking of MAS is introduced to the complex process control system composed of multi-fieldbus in this paper. Agent classes with different functions are abstracted from the control system, and the distributed MAS model with parallel algorithm characteristic based on OPC protocol is established. The collaboration control mechanism is expressed using logical relationships such as Sequence, AND, OR etc. in logical mathematics. Similarity is found between the running mechanism of MAS and the parallel and competitive characteristics in multi- processes programming method after comparison. The main function of agents with MAS idea are developed by C++ language and COM technology in an actual project. Also some discussion is given on the opening characteristic of the multi-fieldbus MAS.
