ROTOR FAULT FEATURE EXTRACTION METHOD USING MVMD AND IEDPE (MT)

ROTOR FAULT FEATURE EXTRACTION METHOD USING MVMD AND IEDPE (MT)

To accurately characterize the different operating states of the rotor system, a modified variational mode decomposition（MVMD） combined with instantaneous energy distribution permutation entropy（IEDPE） is proposed to quantify and extract rotor fault features. The parameters of the variational mode d...
