Abstract
The space elevator has been attracting as an alternative transportation between the earth and space. In the laboratory, we have been researching the climber technology to the realization of space elevator. In the space elevator, the attitude control of climbers is very important for ensuring the safety and feeling while riding of passengers. However attitude is influenced by surrounding environment because the climber is supported only by the tether. Generally, there is equipment that is called Control Moment Gyro (CMG) for attitude hold and vibration damping. In this paper, we introduced a control moment gyro unit for the attitude stabilization and we have examined attitude control of the climber using an optimal digital servo system including a disturbance observer.
