AbstractIn this paper, the effectiveness of vibration control is examined by employing tether on the flexible space structures like SSPS (Space Solar Power System). The vibration control is analyzed numerically to simulate the behavior of flexible space structure in a flexible panel-tether system with mathematical description in the partial differential equation, and the effectiveness is shown for the tether tension control. Vibration control experiment is also examined on an experiment model and the result is compared with that of numerical analysis. An actuator is analyzed in its performance to generate a very low tension employed for the experiment of vibration control experiment of this model. It aimed to make a numeric model about the actuator used when the vibration was controlled, to compare with an actual performance, and to optimize it to the control experiment.
