Fault Classification of Rotary Machinery Based on Smooth Local Subspace Projection Method and Permutation Entropy

Collected mechanical signals usually contain a number of noises, resulting in erroneous judgments of mechanical condition diagnosis. The mechanical signals, which are nonlinear or chaotic time series, have a high computational complexity and intrinsic broadband characteristic. This paper proposes a...
