摘要
In this paper, we extend the forgetting factor least squares and finite-data-window least squares identification algorithms, develop a finite-data-window least squares algorithm with a forgetting factor for dynamical system modeling, derive its recursive version, and also give its simplified form. We illustrate the advantages of the proposed algorithm with simulation examples. (c) 2006 Elsevier Inc. All rights reserved.
