A virtual temperature sensor for an infrared dryer

Keywords: temperature virtual sensor, artificial neural network, infrared dryer, radiation


This paper aims at introduction, design and validation of a temperature virtual sensor for an infrared dryer. As proposed in this article, a virtual sensor is an algorithm to estimate the temperature at one or some points in a thermal system (e.g. an infrared dryer) based on the measured temperature at a number of other points. In this research, the designed algorithm estimates the temperature of a single point; however, the methodology can be evidently extended to multiple points.  Inspired by direct and inverse heat transfer models, a mathematical model is presented for virtual sensing. This model is developed and identified using artificial neural network (ANN) technique and laboratory experimental data. The proposed method exhibits excellent accuracy with no need to thermo-physical properties of the system.
