A new fuzzy control method is proposed for the mold level control in continuous casting process. The method uses a simplified fuzzy PID structure, which combines the advantages of the traditional fuzzy PI and fuzzy PD control methods. The simulation results show that this method has a good effect of suppressing periodic disturbance and has strong robustness to the change of process parameters
