1. A pouring control method for an automatic pouring device with a pouring ladle, wherein the device can control movements of the ladle in back and forth and up and down directions, and can also control its tilting, wherein the method comprises:

  • setting a target flow rate of molten metal to be poured,applying a voltage input to a tilting motor so as to reach the target flow rate of the molten metal based on an inverse model of a mathematical model of molten metal that runs out of a pouring ladle and an inverse model of the tilting motor,estimating a flow rate of the molten metal that runs out of the ladle, andestimating a falling position and getting the estimated falling position to be a target position, and generating a trajectory for movement of the pouring ladle wherein the trajectory causes a height of a lip of the pouring ladle above a level of a sprue of a mold to decrease and causes the ladle not to strike any object located within a range of its movement, whereinthe method controls the movement of the pouring ladle to pour the molten metal into the mold so that the height of the lip of the pouring ladle above the level of the sprue of the mold decreases and so that the ladle does not strike any object when the molten metal is being poured into the mold.
