Performance Evaluation of Models, Identified by the Least Squares Method
1984 (English)Report (Other academic)
The least squares method is widely used for the identification of linear, dynamical systems. Here we investigate how the variances of the estimated models affect their performances in various applications, such as transfer function accuracy, prediction, minimum variance control and pole placement servo control design. Some newly developed asymptotic expressions for the variances are applied. Also, some consequences for the choice of input spectrum and model orders are drawn.
