基于故障树和模糊推理的故障诊断研究

Research of Fault Diagnosis Based on Fault Tree Analysis and Fuzzy Reasoning

针对地空导弹武器装备结构复杂,用传统专家系统进行故障诊断时存在知识获取困难和推理效率低的问题,提出了一种基于故障树分析和模糊推理相结合的智能故障诊断方法。对某型地空导弹武器装备的故障分析诊断表明,该方法具有诊断速度快、诊断结果准确率高的特点,有效实现了装备故障的智能分析诊断。

Considering the structure complex of surface-to-air missile system,for solve the problem of knowledge-get difficulty and inefficient reasoning in traditional fault diagnosis expert system,an intelligent fault diagnosis method based on fault tree analysis and fuzzy reasoning is put forward.The practice of fault analysis and diagnosis for a new kind of surface-to-air missile system shows that the method,which has the characteristic of fast diagnosis and high rate of right result,can efficiently realize the intelligent fault analysis and diagnosis.
