    Método de Sintonia de Controlador PID de um Sistema de Carregamento de GLP
    (Universidade Federal do Pará, 2018) CALDERÓN JÚNIOR, Nibson Müller; NASCIMENTO, Manoel Henrique Reis
    PID controllers are increasingly present in various industrial processes. However, many control loops present tuning failures. This study proposes a methodology for modeling and analyzing industrial plant control systems based on real data, aiming to improve efficiency and optimize plant parameters. The tuning of the PID controller parameters was performed by identifying the dynamic model of the flow control of the LPG loading pump in a propane vessel loading terminal. The plant transfer function was obtained using the Process Reaction Curve method, applying a step disturbance to the manipulated variable (pump rotation). Simulations were conducted using the MATLAB/SIMULINK platform to ensure controller performance, with tuning adjustments made via MATLAB/PID Tuner. The results demonstrated that the adjusted PID controller successfully maintained the controlled variable at predetermined values, optimizing system performance.
