The fault diagnosis of hydraulic pumps is currently important and significant to ensure the normal operation of the entire hydraulic system.

Considering the nonlinear characteristics of hydraulic-pump vibration signals and the mode mixing problem of the original Empirical Mode Decomposition (EMD) method, first, we use the Complete Ensemble EMD (CEEMD) method to decompose the signals.

Second, the time-frequency analysis methods, which include the Short-Time Fourier Transform (STFT) and time-frequency entropy calculation, are applied to realize the robust feature extraction.

Third, the multiclass Support Vector Machine (SVM) classifier is introduced to automatically classify the fault mode in this paper.

An actual hydraulic-pump experiment demonstrates the procedure with a complete feature extraction and accurate mode classification.
