Model order reduction using eigen algorithm

Abstract

An order reduction method has been proposed for reducing the order of the large-scale dynamic systems where denominator polynomial determined through Eigen algorithm and numerator polynomial via factor division algorithm. In Eigen algorithm, the most dominant Eigen value of both original and reduced order systems remain same. The proposed mixed method confirm stability of the reduced model if the original system is stable and has been also compared in quality with other existing model order reduction methods.
