Abstract
Disclosed is a control system for a melting process in an electric arc furnace for melting a metallic material that minimizes desired process properties such as the melting time or the total power consumption of the melting process. The system includes a processing unit adapted for receiving or collecting measured data of at least one process variable, determining the current state of the process, performing an optimization of the melting process, determining a process input based on the result of the optimization, and controlling the melting process with the process input. A method is also presented herein.
