To solve the problem with a large time delay in combined control systems, it is proposed to introduce an additional control circuit for the speed of paper pulp intake. The introduced circuit will function alternately with the current pressure control circuit inside the pressure device.

The pressure device of a paper machine (BDM) is a rather complex object of regulation with many internal and external connections, requiring modern, intelligent algorithms and control systems. The introduction of such automated process control systems is constrained by high requirements for the qualification of service personnel. Thus, the goal is to obtain adequate models of the pressure device on the basis of a production experiment and simulation, to reduce and validate them, which will allow using traditional regulators and control methods.
