This paper is concerned with the pouring control of tilting-ladle-type
automatic pouring systems in casting industries. A new approach to the
modeling and control system of the pouring process is proposed. In the
approach, the flow rate model is described by a nonlinear system with
hydrodynamics. The flow rate control system is built by a feedfoward
control using the inverse dynamics of the flow rate model. In this control
system, control parameters are obtained from the shape of the ladle.
Therefore, the present approach does not reqpuire many experiments to
obtain the control parameters. In addition, this system enables application
for ladle with a complex shape. The proposed method is applied to a
tilting-type automatic pouring system with a cylindrical ladle, and the
effectiveness of the present system is then demonstrated through
experiments.
