Method for producing a metal workpiece

A method for closed-loop control of a chemical process may involve acquiring process data with sensors, transferring the process data to a control system via a fieldbus, transferring a subset of the process data to a computer system that includes a simulation program for stationary and dynamic process simulation of the chemical process, a closed-loop control program for implementing a closed-loop controller, and a memory for storing simulated state variables, cyclically repeatedly calculating and storing the simulated state variables of the chemical process by the simulation program from the subset of the process data, transferring a setpoint value of a control variable of the chemical process to the closed-loop control program, reading a subset of the simulated state variables for input into the closed-loop control program, ascertaining a manipulated variable to achieve the setpoint value by the closed-loop control program, and transferring the calculated manipulated variable to the control system.
