| 摘 要： | 针对民航飞机系统故障诊断的复杂性以及民航对快捷性和安全性的要求,采用了基于优先权值的模糊Peti网(PFPN)的故障诊断模型对某型号飞机空调系统进行故障诊断,以提高诊断过程的快速性和准确性.利用概率统计分析数据得到模糊产生式规则并建立模糊petri网,根据正反向推理相结合的算法,在反向推理中引入表示故障严重程度的优先权...

| Abstract: | For the complexity of civil aircraft system fault diagnosis and Civil's requirements of fast and security,this paper proposes a model of fault diagnosis based on fuzzy Petri nets introducing priority values to improve quickness and accuracy of diagnostic process.The datas are analyzed by probability and statistics to generate fuzzy production rules and to establish fuzzy Petri nets.Based on the backward-forward reasoning algorithm,In backward reasoning,the priority value representing the severity degree of ... |
