CONTROLE DE UMIDADE PI EM UMA INDÚSTRIA DE PROCESSAMENTO DE SOJA: COMPARAÇÃO ENTRE CONTROLE AUTOMATIZADO E CONTROLE MANUAL DE VENTILAÇÃO

This action search presents the results of tuning the parameters of a PI controller based on identifying the dynamic model for controlling a fan in a soybean crushing unit. The unit's transfer function was obtained using the Process Reaction Curve method, by applying a step disturbance to the controlled variable (fan speed). This change contributed significantly to the reduction of defects and standard deviation of moisture, bringing greater stability to the soybean crushing process.
