Background. In modern realities, the issue of import substitution and modernization of existing domestic equipment and control systems in all branches of production and industry of the Russian Federation is becoming more acute. The purpose of this work is to find ways to modernize and improve the automated control system of paper production on the example of the current paper-making machine of the Penza paper mill of JSC "MAYAK". Materials and methods. The paper uses methods of modern theory of automatic control and automation of technological processes, methods of digital image processing, computer modeling. Results. A computer model of an automated process control system has been created that regulates the weight of a paper web on a paper machine. Conclusions. The considered ways of improving the automated process control system of paper production have proved their viability. The use of an automated process control system with a speed ratio regulator allowed to improve the quality of process control, reducing the effect of time lag on the system.
