This paper concerns control of the pouring process of tilting-ladle-type automatic pouring systems used in the casting industry. Here, the flow rate is modeled mathematically using mass equilibrium and Bernoulli’s theorem, then a feedforward flow rate control system is constructed by using the flow rate model’s inverse dynamics. The proposed control system can improve the accuracy of the flow rate, and enables flow rate control to be designed systematically for the various types of ladles used in casting plants. In order to verify the effectiveness of the proposed control system, the system was applied to an automatic pouring system which was tested experimentally using both water and molten metal.
