Frequency domainErrors-In-Variab les estimation oflinear dynamic systems using datafromoverlapping sub-records
Johan Schoukens · 2007
Inthis paper, westudy theconsistency ofaFrequency do- mainErrors-In-Variables estimator using dataextracted fromover- lapping sub-records. Weshowthat consistent models canbefound using periodic excitations. Onlytwoperiods ofthesteady state re- sponse areneeded toextract allrequired information fromthedata. Thisisdoneusing overlapping sub-records. Moreover, thesystem identification procedure used fordataextracted fromindependent ex- periments isshowntobevalid fordataextracted fromoverlapping sub-records. Thisallows theusertoreduce themeasurement time considerably without changing theidentification procedure.
