연속 압연기의 실시간 Hardware-In-the-Loop 시뮬레이터 개발

Because the rolling control technology depends on foreign mill maker, the leaking of rolling control information of POSCO’s characteristic steel is quite serious. And control technicians have problems of applying new control algorithm to real control system due to concerning rolling operation trouble. They also have difficulties of verification of new control logic without test bed instead of real rolling mills. In this paper, we introduced the development of real-time tandem rolling mills simulator for mill controller developers. To give solution to problems mentioned above, the hardware-in-the-loop typed simulator(HILS) including real controller (Siemens PLC) was developed.
