A Hybrid Approach for Model Order Reduction of A MIMO System

Abstract

In this paper, a hybrid model order reduction strategy is proposed to obtain the reduced order model of a  multiple input multiple outputs (MIMO) power system. . The proposed hybrid technique involves the use of Routh approximation and factor division approach for the denominator and numerator polynomials, respectively. The proposed  technique preserves pivotal parameters such as stability & initial time moments of the higher-order model after reduction.  The effectiveness of the proposed method is compared with the existing methods using Integral square error (ISE). Also, reduction in computational time is achieved by the proposed approach as observed from  the MATLAB profiler.
