Sloshing analysis and suppression control of tilting-type automatic pouring machine

This paper presents a two degree-of-freedom control that allows the molten- metal of tilting-type pouring machine to attain the requested angle during the backward-tilting portion of its cycle and to reduce the sloshing (liqui d vibration) caused by this motion. To this end, the feedforward part is co nstructed using the input shaping method and a feedback compensation is per formed based on the H-infinity loop shaping method. Furthermore, two kinds of model are used and useful ways of applying two different models to the s ame problem is presented with the aim of integrating fluid analysis and con trol design.
