This second report is studies on the methods of the controls of liquid surface wave in the case of an incline-type automatic pouring machine. The incline-type automatic pouring machine has two inputs, transfer for going to pouring place and rotation for pouring into the molds. The model is linear state equation model. When rotation and transfer generate waves, we made a one-mode model. First wave model parameters generated by rotations and transfers are identified by using frequency distribution data and the curve fitting approach, which is the least square mothod, by using the steepest gradient method. When rotation and transfer generate waves and the transfer pattern is previously known, a preview control method can be applied. The transfer pattern is fixed, so the transfer pattern can be used to reduce waves. The method is calculating the feed forward preview coefficients for rotation by using the optimal partial differential equation. Finally we demonstrated the usefulness of the approach presented in this paper through several control simulations and experiments.
