Abstract
A method for controlling a ladle to pour molten metal into a sprue of a mold. The method includes obtaining a mathematical model describing a locus of positions where the molten metal flowing from the ladle drops on an upper surface of the sprue. The method further includes solving an inverse problem of the mathematical model, estimating a position where the molten metal drops using a result of the solving of the inverse problem, and determining target voltages to be supplied to servomotors controlling the ladle. At least the target voltage to be supplied to one of the servomotors is determined based on the estimated position. The method also includes controlling the servomotors based on respective target voltages.
