A Sparsity-Promoted Method Based on Majorization-Minimization for Weak Fault Feature Enhancement

Fault transient impulses induced by faulty components in rotating machinery usually contain substantial interference. Fault features are comparatively weak in the initial fault stage, which renders fault diagnosis more difficult. In this case, a sparse representation method based on the Majorzation-...
