| Abstract: | In this paper, a direct one-step method to get discrete reduced order model from high order continous model is presented. The concepts of Frequency fitting redundance and key equations are proposed at first. The superiority of using key-point fitting strategy in one-step model reduction is discussed. Based on the concept of frequency fitting redundance, an intelligent point fitting algorithm is proposed. which effectively minimizes the non-linear error functions derived from one-step model reduction. |
