| Abstract: | The on-line identification for linear systems is a question of common interest in the field of identification.A variable-order recursive extended least squares method and a new criterion of order estimation are derived in the paper.On-line identifier for a class of ARMA models is formulated on the basis of these methods.This identifier can be used off-line modeling.The results of the experiments proved that the methods of the paper are available with less calculation of the modeling. |
| Keywords: | variable-order recursive algorithm on-line identifier modeling |
