The paper constructs a method for identification of models given in partial fraction representation by using a specific discrete bi-orthogonal system of functions specified by the poles and their multiplicities. Using frequency domain data, an iteration algorithm convergent in second order is given that incorporates procedures for finding not only the pole locations, but also their corresponding multiplicity.
