Outline of Final Research Achievements

Vibration control for space structures is important, and the demand for high-performance vibration control is high. In this study, we worked to create an integrated control theory that combines semi-active vibration control and predictive control, with the aim of achieving [low energy consumption] and [high vibration control performance] of semi-active vibration control. The energy-recycling semi-active suppression, which the research group has been conducting, and the predictive control for predicting future vibration states were integrated. Although it was difficult to construct an integrated theory in the conventional concept, the future state of semi-active vibration control can be predicted, and an integrated control theory can be constructed. We clarified the vibration control and prediction performance of the constructed the integrated control theory combining semi-active vibration and predictive control.
