Identification of transfer functions from surge motion response of a semisubmersible platform using time-varying NARX model

Identification of transfer functions from surge motion response of a semisubmersible platform from model test data is presented in this paper. The identification is carried out by estimating the time-varying model coefficients of a time-varying NARX (TVNARX) model. The coefficients are estimated usi...
