Abstract

The electric power panel is widely used in aircraft engineering. Extracting the degradation feature of power panel is very important for degradation modeling and RUL estimation. This paper employed an Ensemble Empirical Mode Decomposition (EEMD) based method to extract the degradation statistics feature of power panel. First, the degradation data is decomposed into independent Intrinsic Mode Functions (IMFs) by EEMD. Each IMF contains the information of degradation and fluctuation. The FFT and Chow test method is applied to extract the information of periodicity and mutability characteristic respectively. Based on this, the characteristic series of each IMF can be constructed. Secondly, the main characteristic is identified by correlation coefficients analysis which is utilized to identify the main characteristic by comparing the characteristic series and corresponding IMFs. Finally, the results are carried out and compared with that of using wavelet packet decomposition (WPD) to verify the efficiency.
