Fuzzy_entropy_bbd
模糊熵, 为解决从信号中提取故障特征难的问题, 介绍了一种新的信号故障特征提取方法—— 多尺度熵( multi-scale
entro py, 简称MSE) , 并将样本熵和多尺度熵分别应用于转子故障信号复杂性的度量, 以提取故障特征。试验数据
分析表明, 与样本熵相比, 多尺度熵更能有效地实现转子故障类型的诊断。(A new rolling bearing fault diagnosis approach based onmultiscale permutation entropy (MPE), Laplacian score (LS), and support
vector machines (SVMs) is proposed in this paper. Permutation entropy (PE) was recently proposed and defined to measure the
randomicity and detect dynamical changes of time series.)
