Abstract: Introduction was made to the online control functions of wire rod water-cooling. This paper analyzed the requirements of the hardware and software in the process of wire rod water-cooling and its implementing scheme and gave the system structure schematic of the pulling-on water-cooling technique control. Via constructing the automatic control system based on PLC S7-300, the system realized fuzzy PID control scheme. The simulation results show that adopting fuzzy PID control reduces overshoot with better anti-interference capacity. The concrete scheme of programmable logical controller is used to realize the control strategy to optimize the process of watercooling.
            Key words: fuzzy PID; wire rod water-cooling; MATLAB simulation; hardware configuration
