Abstract

The article describes the design and modeling of an automated control system (ACS) based on the UPM controller algorithm for controlling the heat treatment of cocoa beans in a belt conveyor dryer. Heat treatment processes are modeled as a continuous, spatially distributed system with one input and one output, where the controlled variable is the temperature of the incoming drying air, and the controlled variable is the temperature of the product in the drying chamber. The requirements for the software and hardware of the automated control system are presented and discussed. The numerical simulation of the automated control system was carried out using the Matlab application software package. The results of numerical simulation are presented, confirming that the UPM controller is stable and stable with respect to input interference. It is shown that the system provides a rapid response to displacement and elimination of the steady-state error during heat treatment.
