Abstract

An improved curve fitting technique, based on modification of work by Levy and Sanathanan and Koerner, incorporating known physical constraints is described. A comparison with experimental results on high-order systems shows that there is a much better guarantee of obtaining stable transfer functions and of predicting responses in other domains.
