概要

In order to enhance a control effect for suppressing an impact vibration, a new active vibration control method, that is, a pole-zero active vibration control method, was proposed by the authors. It is the purpose of this paper to realize the vibrationless forge system with the pole-zero active control and to verify the capabilities of the proposed method. First, this paper investigates the control effect of a pole control method constructed by using a feedback control. Then, adding a zero control method in terms of a feedforward control to the system, the pole-zero active control method is realized, and its effectiveness for the suppression of impact vibration is demonstrated. Next, with a view to clarifying the robustness of the control system, the effects of experimental conditions such as test-piece material and dropping stroke of a hammer-head are discussed.
