Abstract
This article discusses the process of copper smelting in a Vanyukov furnace, with special attention paid to maintaining the optimal melt temperature, which is a key factor in the stable operation of the furnace. The article presents the results of experimental studies conducted at the Balkhash Copper Smelter, as well as experimental statistical data on the input and output parameters of the automated process control system (APCS). To build a mathematical model of the process, the System Identification Toolbox package in the MATLAB environment was used. As part of the work, modeling was carried out using a PID controller, its parameters were optimized to minimize the mean square error of regulation. In addition, the effectiveness of a fuzzy controller was considered, which showed a decrease in the dynamic error and a smoother process.
