Abstract
This paper proposes a new method for controlling vibrations using the interactive force of a pair of identical flexible structures arranged in parallel such as solar panels of a space station. The key feature of this new method is to connect to arms with the actuators to different positions on a two flexible structures. The modes of bending from first to third and first torsional mode are well controlled using our proposed modeling method and a filtered LQ control theory. Computer simulations and control experiments are carried out and the effectiveness of the mechanism presented is confirmed.
