Abstract
A mixed method is proposed for finding stable reduced order models of single-input- single-output large-scale systems using Factor division algorithm and the clustering technique. The denominator polynomial of the reduced order model with respect to original model is determined by forming the clusters of the poles of the original system, and the coefficients of numerator polynomial with respect to original model are obtained by using the Factor division algorithm. The mixed methods are simple and guarantee the stability of the reduced model if the original system is stable. The methodology of the proposed method is illustrated with the help of examples from literature.
