Abstract

The control of the surface temperature of ceramic tiles in a real industrial production line is developed. The process consists of a transportation band that carries the hot tiles through a water sprayer whose objective is to reduce its temperature. The regulation of the quantity of water deposed (and hence evaporated) per tile allows to control the output surface temperature. This quantity is regulated by changing two variables: the velocity of the transportation band and the flow of the sprayer. First,the experimental identification of the process model is carried out. Then,a static control based on the measurement of the input temperature is proposed and tested in the plant. Finally,an adaptive control based on the measurement of the input and output temperatures is developed and also tested in the plant,showing a much better performance
