Real measured data obtained from in situ measurements are used in the validation study. The system model used in the strain estimation is constructed based on the mode shapes and natural frequencies obtained from a finite element model of the structure and the damping characteristics that are obtained from a prior output-only operational modal analysis (OMA) of the tower. A recently developed approach for quantification of the estimation uncertainty introduced by sensor noise and unknown excitation acting on the structure is applied. The approach is used to determine the noise statistics for Kalman filtering that minimize the estimation uncertainty. Finally, the quality of the strain estimates is assessed by comparison with the actual, measured strains. Very accurate strain estimates are obtained.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Kalman filter based strain estimation for fatigue assessment of an offshore monopile wind turbine","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2017-05-31","DateCreate":"2017-05-16","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":"WOS:000392486303011","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":285670,"PubliDate":2016,"Pagination":"1649-1661","XtraPublOfAnaID":null,"ISBN":"9789073802940","Volume":null,"Issue":null,"BRefMon":285873,"BRefMonRR":"<b>Sas, P. <i>et al.</i> (Ed.)</b> (2016).
