In order to realize geomagnetism aided navigation (GAN) in the regions with insignificant geomagnetic characteristic, inspired by the pattern recognition idea, the geomagnetic matching (GM) problem was transformed into statistical pattern recognition and was analyzed from the aspect of pattern recognition. A matching algorithm based on support vector machine (SVM) was proposed. The selection of training...
Empirical Mode Decomposition (EMD) is a decomposition algorithm which is used to analyze signal. In this paper, a new fault diagnosis approach, which is the EMD based on the optimization of noise reduction, is proposed for bearings. Firstly, the original signal is decomposed into a set of Intrinsic Mode Functions (IMFs) by EMD combined with Genetic Algorithm (GA) for reconstruction. Then effective...
