Abstract :
The computer control system of a steel plant is composed of Siemens S7-400 PLC and configuration software WinCC. In order to achieve real-time control of water flow accurately in quenching process, this paper uses a combination of Smith predictor and PID controller to compensate time delay of system and overcome problems caused by the delay. MATLAB simulation verifies that this method can solve the time delay problem in quenching process, and provide a solution for real-time control of water flow.
