摘要
论文将有限元建模与面向控制的频域辨识结合起来应用于挠性结构振动主动控制的建模中 ,并对辨识的输入信号进行分析研究 .以挠性悬臂梁为例进行了模型辨识 ,利用物理实验系统进行控制和验证 ,结果表明 :对于挠性结构 ,频域辨识能得到针对控制的、效果很好的数学模型 .
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.
