提出了基于直接速度反馈控制（DVFC）的辨识方法，并将其应用于柔性结构的鲁棒振动抑制控制。首先对柔性结构进行伪被动控制，并利用变结构控制器实现伪被动控制。如果传感器和致动器并置，则DVFC的行为就像机械阻尼器。接下来，系统识别应用于修改后的结构。通过该过程，更容易导出用于振动抑制控制的精确结构模型，而不考虑采样时间、识别模型及其阶次。因此，不确定性，如参数误差和未建模的动态可以表示。最后，通过典型地震荷载和柔性结构振动抑制控制的实验结果，验证了该识别方法的有效性。
This paper proposes direct velocity feedback control (DVFC)-based identification along with its application to robust vibration suppression control of flexible structures. At first, a flexible structure is modified by pseudo-passive control which is realized by DVFC. This DVFC behaves just like a mechanical damper if the sensor and actuator are collocated. Next, system identification is applied to the modified structure. Through this procedure, the accurate structure model for vibration suppression control is more easily derived without paying regard to a sampling time, an identification model and its order. Consequently, the uncertainty such as parameter errors and unmodeled dynamics can be expressed. Finally, the effectiveness of this identification method is verified through the experimental results primarily for a typical earthquake loading and additionally for vibration suppression control of a flexible structure.
