DVFC-Based Identification and Its Application to Robust Vibration Suppression Control of Flexible Structures
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.
