A Method for the Reduction of Linear High Order MIMO Systems Using Interlacing Property and Factor Division Technique

This paper presents a new mixed method for the reduction of linear high order MIMO system. This method is based upon the interlacing property by which the denominator polynomial of the reduced order model is obtained and the numerator is obtained by using factor division method. In general, the stability of the high order system is retained in their models. Better approximation of the time response characteristics is attained by using this suggested method. The number of computations has been reduced when compared to several of the existing methods are in international literature. Another advantage of this method is that it is a direct method. The suggested procedure is digital computer oriented.
