X. He et G. Deroeck, SYSTEM-IDENTIFICATION OF MECHANICAL STRUCTURES BY A HIGH-ORDER MULTIVARIATE AUTOREGRESSIVE MODEL, Computers & structures, 64(1-4), 1997, pp. 341-351
This paper presents an algorithm for a time series analysis-the high-o
rder multivariate autoregressive model M-AR(P). The theory of the mode
l and the application in modal parameter identification of structures
excited by natural random forces is described. A water transmission to
wer is taken as a real example to illustrate the application procedure
of this algorithm. Good results in natural frequencies, damping ratio
s, mode shapes, as well as power spectra and coherence functions ident
ified by this model prove the advantages and usefulness of the algorit
