In high performance active vibration control for a flexible structures, it is requirement to establish an accurate model identified not only 1^<st> but also 2^<nd> and 3^<rd> vibration modes of the flexible structure. This paper presents the derivation method of modal parameters of flexible structures based on system identification theory. In this identification, multi-decimation(MD) operation is applied to identify wide frequency region in a short vibration time accurately. By using circle curve fitting on each identified mode, modal parameters can be derived from MD identified models. We apply the proposed identification method to the three-story structure, and we show, the effectiveness of the proposed method through the identification experiments.
