Abstract :
This paper describes a numerical linear algebra algorithm to compute the dominant poies of multiinput/multioutput (MIMO) high-order transfer functions. The results presented are related to the study of electromechanical oscillations in large electric power systems, but the algorithm is completely general. The computed dominant poles may then be used to build modal equivalents for MIMO transfer functions of large linear systems, among other applications.
