Abstract

It is well known that the least squares estimation of ARMAX models is biased. In this paper, by combining the principle of bias compensation and hierarchical identification, a new identification is established for this equation error model with moving average noises. The proposed estimate of the system parameter is given by the least squares estimate modified by a correction term. A numerical example is employed to show the advantage of the proposed estimation algorithm.
