357 Driving at Resonance Point of Multi-Degree-of-Freedom System by Decentralized Control : Formation of Self-Excited Vibration Mode by Adding Cross Feedback Control

Abstract

We study about a control method of efficiently exciting a multi-degree-of-freedom system at a resonance frequency. But only local feedback control cannot form all of vibration mode when degree-of-freedom of a system increases. So we thought a control method adding cross feedback control to local feedback control to be formed all of vibration mode. At first, we verified experimental apparatus drives at all of the natural frequency by adding cross feedback control. Additionally, we verified whether the vibration mode can be maintained for adding excitation signal. Finally, we verified can be driven at resonance point for changing mass and dumping.
