| Abstract: | This paper presents a design and implementation of an expert system for real-time fault diagnosis of complex chemical processes.Structure of the system,a structure of knowledge base and a design of inference machine are discussed in detail.A new strategy of conflict resolution of knowledge rule sorting strategy of antecedent as well as a selection strategy of knowledge rule in a memory knowledge base is presented.To take a lubrication processes for example,a diagnosis process of the system has been discussed.The application of the system has shown that it has responded with the process fault immediately and satisfied requirement of a production. |
