Title:Monitoring procedure in frequency domain using intensity estimation of the energy of the envelopeAuthor(s):Kurt Pichler, Luigi del Re, Andrea Schrems, Martin WürteleAbstract:In this paper a monitoring procedure for a rotating machine is presented, based on a frequency domain approach. The energy content of several frequency regions is evaluated by analyzing the spectral envelope of 2-dimensional acceleration measurements mapped into higher-dimensional space. It is shown that such a monitoring procedure is feasible under non conservative restrictions. The paper ends with three industrial relevant examples where the monitoring procedure is illustrated.Booktitle:Proceedings of the 15th IFAC Symposium on System Identification, SYSID 2009Page Reference:6 page(s)Publishing:2009Series:System IdentificationVolume:15Number:1
