Simulação de uma automação nas empacotadoras da empresa, através de um controlador PID, como forma de facilitar o controle de sobrepeso

Abstract

This work presents the development and simulation of an automatic control system for oatmeal sachet packaging machines, aiming to reduce overweight packages. The current process, which relies on manual adjustment of a volumetric dosing wheel, leads to inaccuracies and product losses. The proposed solution employs a P&ID controller implemented in MATLAB/Simulink, with tuning performed using the P&ID Tuner tool. The system model incorporates the variability of the apparent density of oats and simulates the dynamic behavior of the dosing system, represented by a first-order transfer function with delay. Results demonstrate that using optimized parameters leads to reduced overshoot, faster stabilization, and better compliance with the desired setpoint. The study also discusses the technical challenges of physical implementation, such as the need to reposition the weight checker, replace manual adjustments with high-precision servomotors, and the limitations caused by the simultaneous operation of the four dosing cups. Despite these challenges, the proposed approach shows potential to improve efficiency, reduce waste, and enhance production standardization.
