多自由度除振装置のシステム同定手順に関する一考察(機械力学,計測,自動制御)

This paper considers a system identification procedure of multi-degrees-of-freedom anti-vibration apparatus. A general procedure of system identification requires the determination of some parameters such as model structure, model order and sampling frequency of I/O signal. Although general guidelines for the determination of these parameters have been studied and reported, some of the parameters should be selected and determined through trial and error in practical engineering fields. Discussing the determination guideline of these parameters is quite useful in order to make a system identification technique applicable in practice. In this paper, the influence of some parameters on system identification results are discussed through the comparison of frequency responses of the models obtained by subspace method under different conditions. These consideration contribute to the application of a system identification technique in practice.
