摘　　要：通过分析导弹电液伺服机构结构组成与工作特性,设计了基于专家系统的故障诊断方案;介绍了故障诊断专家系统的设计总体思想、硬件组成和软件模块,详细说明了诊断知识的两种表示方法,并且通过在推理过程中增加中间数据处理模块实现了动态数据与静态数据的比较,从而为故障诊断提供了便利条件。The fault diagnosis project based on expert system is designed through analyzing the structure and working characteristic of missile electro--hydraulic servo mechanism. The design general idea of fault diagnostic expert system, hardware composing and software modules are introduced, and the two kinds of diagnostic knowledge expression methods are explained particularly. The comparison between dynamic data and static data is realized by adding middle data disposal module in reason process so that it can offer the convenient condition for fault diagnosis.
