This paper presents a method for damping sloshing in a liquid container during its transfer by a cart that is equipped with an active vibration reducer with six-degree-of-freedom parallel linkage. Sloshing is generated during the liquid container transfer. To damp this sloshing, it is tilted and horizontally moved by the active vibration reducer. The reducer is controlled by a linear quadratic regulator. A weighting matrix of the quadratic performance index is optimized using a genetic algorithm. Gain scheduling is used to apply it to any liquid level of the container. The cart is driven along a straight path on a horizontal plane. The usefulness of the control system is verified through a simulation and experiment.
