In this paper, we describe a method for vibration suppression of multi-mode vibration system. This is the method which combined a filter to pick signal of fixed transfer function out with a general differential controller. It's possible to pick only signal of fixed transfer function out from output signal and feedback it by this filter.In this paper, we indicate the algorithm of the proposed method, and confirm the effect of vibration suppression by simulations and experiments. We confirmed that the proposed method can suppress the first mode vibration of the plant by step response and disturbance response simulations. Further, we performed verification experiments and confirmed that it's possible that the proposed method suppresses the first mode vibration of the plant by measurement results of frequency response and step response. From these results, we showed the validity to the vibration suppression of the proposed method.
