摘要:
设计了一种基于故障树的专家系统结构,建立了自动驾驶仪系统的故障树模型和专家诊断知识库,提出了一种基于故障树专家系统的自动驾驶仪系统故障诊断方法,开发了基于该方法的故障诊断实验平台。该方法通过对自动驾驶仪系统故障树模型进行分析,提取故障树最小割集及最小割集重要度,将专家系统作为框架、故障树作为诊断规则,并存入专家系统知识库,运用基于故障树最小割集重要度的推理机,实现故障树与专家系统的交互操作,最后完成诊断并输出结果。
Abstract:
Fault diagnosis is one of the hot topics in the field of the autopilotsafety.A diagnostic expert system(ES)for the autopilot s based on fault tree analysis(FTA)was designed,a fault diagnostic method of the autopilot system including a FTA model and a diagnostic knowledge database was introduced,and a platform of fault diagnostic system was implemented. The method gets the minimal cut sets and the importance of the cut sets by analyzing the FTA of the autopilotsystem,and uses them as diagnostic regulation of expert system. The fault tree accomplishes interaction with the expert system by using importance of the minimal cut sets,and outputs diagnostic results finally.
