MODELAGEM DE PID PARA SISTEMA DE CONTROLE DE RAMPAS DE TEMPERATURA EM BRASSAGEM

The aim of this paper is to present a strategy for modeling a heating process where it is necessary to follow specific temperature slopes with focus on mashing tuns for nano brewers. In this situation, the heating element is generally represented by electric heaters or gas, both on/off, demanding a specific strategy for delivering the amount of power calculated by the PID controller, also described and analyzed in this work. For creating the model, data were empirically obtained by heating proportional volumes of water using a electric boiler.
