基于深度学习的方法解决微小故障已经取得了很大的进展和很好的效果
但是前提要有充足的样本数据
在现有的情况下却难以实现.所以基于传统的数据预处理的故障诊断方法仍然有很好的必要性和现实性.主元分析(Principal Component Analysis
PCA) 被广泛应用在故障诊断中,由于传统的数据预处理方法各有优势和不足,造成特征提取不准确,为此该文提出了一种基于数据变化率(Rate Of Change
ROC)的数据预处理方法以提高PCA在故障诊断中的性能指标.通过变化率变换对原始数据集预处理后,能够有效地检测系统变量中的微小故障.最后,通过仿真验证基于数据变化率的PCA故障诊断方法的可行性和有效性.
The method based on deep learning has made great progress and good results in solving small faults
but the prerequisite for sufficient sample data is difficult to achieve in the current situation. So there is still a good need for the fault diagnosis method based on traditional data preprocessing. Principal component analysis(PCA) is widely used in fault diagnosis. Because traditional data preprocessing methods use the absolute distance between samples as the criterion for fault detection and fault diagnosis
the feature extraction is not accurate. For this reason
this paper proposes a data preprocessing method based on rate-of-change(ROC) transformation to improve the performance index of PCA in fault diagnosis. After the original data set is preprocessed by the change rate transformation
it can effectively detect the minor faults in the system variables. Finally
the feasibility and effectiveness of the PCA fault diagnosis method based on the rate of data change are verified by simulation.
