Order Reduction Using Basic Characteristics And Modified Cauer Continued Fraction
The authors propose a mixed method for reducing the order of the high order dynamic systems. In this method,
the denominator polynomial of the reduced order model is obtained by using the basic characteristics of the higher order
system which are maintained in the reduced model while the coefficients of the numerator are obtained by using Modified
Cauer Continued Fraction. This method is fundamentally simple and generates stable reduced models if the original highorder
system is stable. The proposed method is illustrated with the help of the numerical example taken from the literature.
