Control method is studied numerically and experimentally on vibration of large flexible solar panel for a tethered space solar power satellite by employing tension of tether. The test beds are designed to model free-free beam system which has very low frequency modes of vibrations in its structure. The method is employed to simulate the micro-gravity behavior of the large flexible space structure. The method is to use floating elements to employ through air bearing over a flat horizontal table. In the method, many floating elements are jointed by a flexible beam. (Flexible space structure mock device). The vibration control experiment of the panel by the Tether tension was done by using a flexible space structure mock device and the minute tension actuator. Tether is attached at the end of the corners of the flexible space structure mock device and the tension of tether is controlled by the mission-function algorithm by feeding back the deflection at the end of tether attached at the minute tension actuator. It made comparative study of the experiment result and the numerical analysis result of obtaining, and the effectiveness of the numerical analysis was verified experimentally.
