一个基于混合推理的故障智能诊断系统

首先介绍了用于某导弹系统二次电源故障智能诊断系统的总体框架 ,说明了各模块的功能及开发策略 ,然后介绍了该专家系统中模糊关系矩阵元素的获取方法和规则库的建立方法 ,阐述了模糊推理与规则推理相结合的混合诊断推理方法 ,最后给出了一个系统的运行实例。

AN FAULT INTELLIGENT DIAGNOSIS SYSTEM BASED ON MIX INFERENCE

This paper introduces, in the first place, the overall frame of the fault diagnosis expert system for the secondary power supply of a missile system, explaining the functions and tactics of every part. Then, the method, by which we build the knowledge bases that include fuzzy relation matrix and rules, is illustrated. The system adopts a kind of new inference mechanism, which combines fuzzy inference with rule inference, and makes good use of the advantages of the two methods. Lastly, a concrete diagnostic instance is given.
