AN EVOLUTIONARY LIFTING SCHEME WAVELET PACKET DECOMPOSITION METHOD FOR MECHANICAL FAULT DETECTION IN ELEVATOR SYSTEMS
Abstract
The design procedure of a second-generation wavelet packet decomposition, based on an evolutionary approach, is introduced for industrial fault detection. The procedure has been validated by means of an experimental case study for an induction motor used as traction machine in an elevator system. Preliminary results on three mechanical faults related to ball-bearing show encouraging performance.
