Synthesis of a digital PID controller to control the temperature in the agricultural products drying chamber

Abstract

This article provides information and results of measurement and automatic temperature control with a proportional-integral-derivative controller. A microcontroller including special software is used for automatic control the temperature at a given value. For fixation continuity of changes, an algorithm for controlling the temperature in the drying chamber has been developed. The researched process on a computer model and an algorithm for temperature control in chamber was developed. Based on the analysis, transient characteristics of the drying process were obtained.
