Abstract

The design of Rolling Mill electrical control system is based on Programmable Logical Controller(PLC),in which a high resolution optical encoder is used as speed sensor,the way of variable frequency regulation speed system of vector control is used for controlling the speed of main motors and roller motors,and the PLC is used as the core control unit which keeps the speed of main motors and roller motors consistent.And the practical result shows that the whole system has good regulating performance,stable and reliable performance and simple-maintenance.
