In this paper, we proposed a liquid container transfer system with the robustness for the change of static liquid level. First, nominal model is reasonably decided to suppress the sloshing (liquid vibration) for the change of liquid level, and a reference trajectory is also determined by an optimization method of Fletcher Reeves combined with a clipping-off technique to do so. Secondly, H∞ control theory has been applied to this system to obtain the robustness for the change of liquid level. Through simulations and experiments, the usefulness of the present control system has been demonstrated. Finally, the effectiveness has been also shown by comparing such a conventional control method of LQI control with Kalman filter.
