Abstract :
In this paper, we compare the results of the following frequency identification algorithms: the Sanathanan-Koerner (SK) algorithm, nonlinear least squares via Levenberg-Marquardt method, and the two-stage nonlinear algorithm. We also present a recipe for the application of the two-stage nonlinear algorithm. The emphasis of this paper is on the application and comparison of the algorithms developed in the literature to three case studies
