Development of CMG Active Vibration Control Device for Gondola

Abstract

For reduction of the low-cycle vibration of vehicles such as gondolas which are suspended flexibly, the authors studied the utilization of the control moment gyro (CMG) as an active vibration control device. The CMG is a moment generator using the gyroscopic moment effect and it is applied to attitude control of spacecraft. Particularly in the very-low-frequency region (less than 1 Hz), it is effective and requires no reaction support.
