Abstract
This paper presents the design of a control strategy based on the active rejection of disturbances, applied to the temperature regulation of a crucible furnace for the aluminum smelting process. For this purpose, the generalized proportional integral control was used, which was designed based on the simplified model of the furnace identified by means of the Matlab PIDtuner app. When applying the designed control to the model, follow-up data were taken from the reference signal and analyzed using the percentage of quadratic error measured. This showed that the generalized integral proportional control applied to the system model obtained a mean square error percentage of 0.433%, and with a 50% variation of the model parameters the mean square error percentage was 2.88%.
