Vibration control of a two-mass resonant system such as a rolling machine is an important problem in industrial applications, because vibration causes a decrease in task accuracy and the destruction of materials. Taking this into the accounts, state feedback control, H8 control, and resonant ratio control based on a lumped parameter system have been researched for the vibration suppression of a system with a flexible mechanism. On the other hand, methods in distributed parameter model need a lot of calculation in time domain design. In this paper, by considering the distributed parameter system in the Laplace domain, a compensator based on a wave equation is proposed. In addition, a two-mass resonant system is controlled using the proposed compensator. The proposed control system with the wave compensator has a simple structure. Therefore, it is easy to set the control parameters in the proposed control system. The effectiveness of the proposed method is verified by experimental results for a two-mass resonant system.
