| 摘 要： | 基于融合的故障诊断技术是近年来针对复杂系统故障诊断需要发展起来的一种新的技术方法,其中决策级故障诊断主要是针对故障的决策内容研究解决融合诊断的方法,其建模及表征方法与特征级融合有相当不同。以导弹为应用对象,对Dempster-Shafer证据理论应用于导弹决策级故障融合诊断的有效性进行讨论,指出冲突证据融合、冲突衡量及证据聚类是应用中需要解决的3个关键问题;探讨了问题的解决方法,给出了相关建议。

| Abstract: | Fault diagnosis based on information fusion is a new technology for fault diagnosis of complex system nowadays. The decision-level fusion for fault diagnosis, which is different from the feature-level in modeling and representation, studies the fusion method for decision content of fault. The aim of the paper is to explore some problems in application, in which Dempster-Shafer evidence theory (DST) is used to decision-level fusion diagnosis of missile fault. Firstly, the validity of this application is argu... |
