研究了一种应用于机载火控系统的具有自学习功能的故障诊断系统。首先介绍了系统的

总体结构 然后通过分析火控系统的结构建立了层次诊断模型 ,并通过示例对诊断系统中知识的表

达方法、 推理方法等问题做了详细的分析 最后详细描述了系统的自学习机制。应用具有自学习功

能的故障诊断专家系统 ,可实现综合化机载火控系统的智能故障诊断。-A study of airborne fire control system used in self-learning function of fault diagnosis system. First, the overall structure of the system are introduced　and fire control system by analyzing the structure of the establishment of a level of diagnostic models, and through examples of the diagnostic system of knowledge representation methods, inference methods, a detailed analysis of the problem　the final detail of the system self-learning mechanism. Application of self-learning fault diagnosis expert system, can achieve integrated airborne fire control system of intelligent fault diagnosis.
