Fault Diagnosis Based on Improved Kernel Fisher Discriminant Analysis
There are two fundamental problems of the Kernel Fisher Discriminant Analysis (KFDA) for nonlinear fault diagnosis. The first one is the classification performance of KFDA between the normal data and fault data degenerates as long as overlapping samples exist. The second one is that the computational cost of kernel matrix becomes large when the training sample number increases. Aiming at the tw...
متن کاملA Fault Diagnosis Method for Automaton based on Morphological Component Analysis and Ensemble Empirical Mode Decomposition
In the fault diagnosis of automaton, the vibration signal presents non-stationary and non-periodic, which make it difficult to extract the fault features. To solve this problem, an automaton fault diagnosis method based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD) was proposed. Based on the advantages of the morphological component analysis method i...

متن کاملGear Fault Diagnosis and Classification Based on Fisher Discriminant Analysis
Gears are the most essential parts in rotating machinery. So gear fault modes diagnosis and levels classification are very important in engineering practice. This paper present a novel method in gear fault recognition and identification using Fisher discriminant analysis (FDA) due to FDA can reduct dimension when analyse signal. The real data collected from a gearbox test rig is used to validat...
متن کاملKernel Local Fuzzy Clustering Margin Fisher Discriminant Method Faced on Fault Diagnosis
In order to better identify the fault of rotor system,one new method based on local fuzzy clustering margin fisher discriminant (LFCMFD) was proposed. For each point on manifold, the farthest point in local neighborhood and the nearest point outside local neighborhood usually constituted the local margin. LFCMFD introduced fuzzy cluster analysis algorithm, eliminated the influence of pseudo-mar...
