The invention relates to an airborne converter electrical fault diagnosis method based on a stack-embedded denoising automatic encoder. The method comprises the following steps: constructing a converter fault diagnosis model based on a stack-embedded de-noising automatic encoder for an airborne converter to be subjected to fault diagnosis; when fault diagnosis is carried out on the airborne converter, fault diagnosis information of the airborne converter in a parameter period is collected; and loading the collected fault diagnosis information to the converter fault diagnosis model, carrying out feature extraction on the fault diagnosis information by using an SDAE fault feature extractor in the converter fault diagnosis model, classifying the extracted fault features, and outputting a fault diagnosis result based on the fault diagnosis information after classification. According to the invention, rapid electrical fault diagnosis of the airborne converter can be effectively realized, the efficiency of fault diagnosis is improved, and support and guarantee are provided for maintenance of fault diagnosis.

    本发明涉及一种基于堆嵌式去噪自动编码器的机载变换器电气故障诊断方法。其包括:对待故障诊断的机载变换器,构建基于堆嵌式去噪自动编码器的变换器故障诊断模型;对机载变换器故障诊断时,采集所述机载变换器在一个参数周期内的故障诊断信息;将所采集的故障诊断信息加载至变换器故障诊断模型,利用变换器故障诊断模型内SDAE故障特征提取器对故障诊断信息进行特征提取,并将所提取的故障特征进行分类,以在分类后输出基于故障诊断信息的故障诊断结果。本发明能有效实现机载变换器的电气故障快速诊断,提高故障诊断的效率,为故障诊断的维修提供支持与保障。
