摘要：
This paper presents an automation scheme for an overhead magnet crane that is a critical component of thick steel plate storage yard automation. First, the load cells and magnetic flux sensors are introduced to detect the number of steel plates lifted using the magnet crane. Then a voltage control algorithm to lift the ordered number of steel plates is proposed and implemented by using the on-line tuning look-up table. Finally, the overall hardware and software description for automatic crane operation is presented. The results have been successfully implemented in POSCO's No. 2 thick steel plate storage yard.
