Abstract
Mathematical modeling is carried out to determine the optimal temperatures in the zones of the material cylinder for the extrusion unit. The transfer function of the material cylinder is obtained. The optimal tuning coefficients for the proportional-integral-differential adjustment law are calculated. Modeling of the temperature control system with optimal controller parameters in the VisSim environment is performed. A graph of the transient process with a PID controller is built. The obtained data of mathematical modeling and calculation of the optimal coefficients for the PID controller can be used to adjust the temperature on the material cylinder in the production of plastic pipes by extrusion.
