Abstract
This paper deals with vibration control using the optimal design strategy of the connected control device for flexible structures with same dynamic properties. One of the authors had already proved effectiveness of connected control method for vibration control of flexible structures arranged in parallel. However, its control performance is degraded as the natural frequencies of structures become closer. To overcome this problem, the authors present a modified control mechanism in which the actuators are connected to the structures with differences in its connecting position by using long arms named "supporting structures". However, the optimal design strategy for vibration control device has not been established yet. In this report, the optimal design strategy of passive control is presented. Computer simulations and the experiments are carried out and the effectiveness of the presented vibration control designed by the connected control device is confirmed.
