EMD自适应滤波信号筛选EMD Adaptive Filtering Signal Filtering



EMD is a new kind of signal analysis theory, which can decompose the signal into the EMD, and get the finite frequency from large to small intrinsic mode function IMF. In essence, it is a kind of space-time filter. In this paper, a method of adaptive filtering based on EMD is proposed, and the method is verified by mathematical simulation and experimental analysis. The results show that the proposed method can effectively extract the vibration fault features and can be applied to the early fault diagnosis of the pump.
