Application Research of Fuzzy Petri Net Expert System in Nuclear Power Plant Fault Diagnosis
-
摘要: 针对传统专家系统存在的知识表达能力不强、推理效率低的问题,采用面向对象的模糊Petri网知识表示方法,对专家系统的知识库进行改进;以此为基础,对专家系统的推理机进行了设计。在核动力装置模拟器上进行仿真试验,结果表明,本文所构建的专家系统能准确地诊断出系统发生的故障。Abstract: The Object-Oriented Fuzzy Petri Net is used as a knowledge representation method for the design of the knowledge base,to improve the traditional Expert System’s ability of knowledge expressing and reasoning efficiency.Based on this,the inference engine of Expert System was designed.A simulation experiment was made with a Nuclear Power Plant Simulator,and the results show that,the Expert System constructed in this paper can diagnose the faults accurately.
