Long-continued vibrations cause the serious damages to architecture and structures. Therefore, vibration suppression is required in various fields of engineering. Predictive control estimates the future state of vibration and determines a control input based on the vibration state estimation. The semi-active vibration suppression is a promising control scheme owing to its robust stability and low-energy consumption. In this study, we propose a new methodology integrating predictive and semi-active controls. The proposed method achieves effective vibration suppression through the future vibration prediction of a target structure. Furthermore, the proposed method not only estimates the future vibration state but also the periodic external force. The efficiency of the integrated method is demonstrated in simulations and experiments. The performance of vibration suppression is evaluated with a variation of a predictive control parameter.
