This paper is concerned with a control design methodology for vibration control of flexible structures by the wave control. In the wave control, controllers are usually designed to minimize the reflection coefficient by utilizing the wave analysis. However, because the method is based on the wave analysis, the method has been mainly applied to simple uniform structures. In this paper, to establish a control design method for more complex systems, we propose a control design method base on the impedance matching index, which represents the difference of the transfer functions of the closed system and the controller. The index is selected from an observation of the facts for the wave analysis and control for uniformly varying ladder networks. Optimal tuning of passive dampers and dynamic absorbers by the impedance matching index is especially considered as a first step for control design. Numerical example of vibration control of a damped mass-spring system with auxiliary masses is conducted to show effectiveness of the proposed method.
