Abstract
We propose a method for selecting the most accurate natural frequency set f rom all of the natural frequency sets; extracted from multiple frequency re sponse sample sets. The accuracy of the natural frequency set is estimated from the proposed fitting error. The method is applied to synthetic data, t he Method of Moments (MM) data and measured data, and variations of the err or of the natural frequencies and the fitting error show an agreement.
