Abstract
The Routh approximation method for model reduction is modified, enabling a reduced-order model to be derived whose numerator order can be selected independently of the order of its denominator. Hence, the proposed method overcomes the hitherto existing problem that the numerator order of the reduced model, derived while applying the Routh approximation, is fixed at one less than its denominator order.Keywords
