In the modern control schemes broadly applied presently in the servo drive system of machine tools; the sampling frequency has been growing larger and larger becomes higher and higher; so it is important to keep up-to-date with the variance of the actual system parameters. As a solution to the problem; a novel method developed from the recursive extended least squares (RELS) algorithm in terms of the computation of functions; operates in such a way that the parameters of the system model are revised only when several proper new groups of data are obtained. The simulation and experimentation of online direct closed-loop system identification indicate that; by selecting the updating step; this method is able to effectively cut down the identifying cost time while obtaining satisfactory accuracy of estimation. © Springer-Verlag London Limited 2006;
