Fault Diagnosis of Excavator Hydraulic System Based on

Application of PCA method and FCM clustering to the fault

Aug 21, 2007 · Abstract: In order to improve reliability of the excavator's hydraulic system, a fault diagnosis approach based upon principal component analysis (PCA) method and fuzzy c-means (FCM) clustering was proposed. PCA is a powerful method for re-expressing multivariate data, which could effectively extract the correlation among process variables.
