Abstract :
In this paper, we use a reduced order model based on a model frequency representation, factor division and an error criterion. We show from the input-output behavior (time and frequency analysis), the interesting properties of this approximate, mainly once we comparing it to several recent model reduction techniques. A criterion is used to well appreciate the distance judge how good is the proposed technique.
