ウェーブレット変換を用いたシステムの動特性同定

抄録

Signal processing of multifrequency channel decompositions should be possible in the near future because signal processing for each frequency channel is easy. However, a difficult problem, i.e., aliasing, exists when the signal is reconstructed. The wavelet transform technique has a special property, i.e., that the signal can be reconstructed uniquely after multifrequency channel decompositions. In this study, a new practical identification method, in which the wavelet transform technique is used, is proposed. This proposed method is used to identify a one degree of freedom pneumatic robot which is developed in this study. The applicability of the proposed method is confirmed by the experimental results.
