In view of the low speed, the heavy load, reversing, the frequently brake, the intense impact characteristics of AOD furnace tilting system, The double closed-loop with feedforward is used. Position regulator and speed regulator use PID algorithm. And the speed loop is designed, based on vector control. This control system was simulated by MATLAB Simulink software. The simulation result showed: Adjustment time is 8s, the position steady-state error is 0, so it has achieved the demanded target of 0.12 radian static error fully.
