Research on Distributed Cooperation Solution Method of Complex Diagnosis System Based on MAS

To adapt the model in reconfiguring fault diagnosing to dynamic environment and the needs of solving the tasks of complex system fully,the paper introduces multi Agent and related technology to the complicated fault diagnosis,an integrated intelligent control system is studied.Based on the thought of the structure of diagnostic decision,hierarchy in modeling,multi layer decomposition strategy of diagnosis task,a multi Agent synchronous diagnosis federation integrated different knowledge expression modes and inference mechanisms is presented.The functions of management Agent,diagnosis Agent and decision Agent are analyzed.The organization and evolution of Agents in the system are proposed,and the corresponding conflict resolution algorithm is given,layered structure of abstract Agent with public attributes is build.System architecture is implemented based on MAS distributed layered blackboard.The real world application shows that the proposed control structure successfully solves the fault diagnosis problem of complex plants.
