Abstract

Abstract: Continuous wavelet transform (CWT) has a finer scale resolution than dyadic discrete wavelet transform and wavelet packet transform. The describing used in engineering is proposed. The method of wavelet is applied to the active control experiments for torisional, flexural and coupling of flexural and torsional vibration. The signals are analysised by CWT. The result is satisfied by using the method and computer program proposed.

Key words: Active control, Torsional vibration, Turbogenerator shaft system, Wavelet analysis
