Abstract
In order to suppress an impact vibration, this paper presents an active control method using a servodamper with a preview action. It is also the purpose of this paper to establish the design procedure of the servodamper system, as well as to verify the capability of the proposed method. First, from the viewpoint of the preview control method, this paper describes system equations of the servodamper system. Then, by using a parameter optimization technique, the necessary conditions for the optimal servodamper system are derived. Moreover, based upon the design procedure, a control on the control effect of the servodamper system are investigated. Furthermore, aiming at a simple control system of the servodamper, a relation between an order of the control compensator and the control effect is clarified. Finally, the robustness of the servodamper system is discussed and a perspective to realize the servodamper system with a preview action is obtained.
