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