| Abstract: | The finite element modeling and control-oriented identification in frequency domain are combined and applied to modeling of active vibration control in flexible structure in this paper. The input signals for identification are analyzed. The identification and the control effect of a cantilever in a physical experiment based on the model are developed to illustrate the idea. It is shown that an effective control-oriented model for flexible system can be obtained by frequency domain identification. |
