Order Reduction using Modified Pole Clustering and Pade Approximations

Authors: C.B. Vishwakarma


The authors present a mixed method for reducing the order of the large-scale dynamic systems. In this method, the denominator polynomial of the reduced order model is obtained by using the modified pole clustering technique while the coefficients of the numerator are obtained by Pade approximations. This method is conceptually simple and always generates stable reduced models if the original high-order system is stable. The proposed method is illustrated with the help of the numerical examples taken from the literature.

Keywords: Stability, transfer function, Modified pole clustering, order reduction, padeapproximation
