Abstract
The space elevator technology has been paid attention as an alternative means of transport in rocket technology. In our research, we focus the drive mechanism of a space elevator climber. In the space elevator climber, researchers had been paid attention to the ascent. Because the descent run costs the same distance as the ascent, the descent is also as important as the ascent. The descent controller should consider gravity acceleration. Therefore, we aim to descending without dropping and vibration. In this paper, we studied the descent speed stabilization control using the disk brake mechanism based on a disturbance observer.
