This paper proposes a new method for the vibration control of structures arranged in parallel. Recently, active dynamic absorbers have been used widely in the field of vibration control, but in the case of vibration control for several structures which stand independently this method is not advisable. In our method, both structures are controlled actively at the same time with a single actuator placed between them. Since supplementary masses are not necessary, the equipment can be simple and light. Here, the optimal design method of the controller for a 1-1 degree-of-freedom system by LQ control theory is shown. Moreover, the problem on the vibration control of the flexible structures is spillover, and this paper shows the application of the reduced-order model which suppresses the spillover in the controller design and its extension to a multi-degree-of-freedom system. Effectiveness of this method is demonstrated by the experiment.
