Proposta de controle de nível em ambiente virtual usando controladores PID

Abstract

This work proposes the development of an integrated level control system in a teaching plant, using the PID (Proportional-Integral-Derivative) technique to optimize process accuracy and stability. The approach replaces conventional strategies, such as PWM (originally applied to power control), highlighting the versatility of the PID controller in dynamic contexts. The methodology involves three main steps: a theoretical review of PID tuning parameters and their application in level systems; simulation in the Simmaq 3D environment, which allows realistic modeling of tanks, sensors, actuators, and control loops; and programming of the ladder control logic in CODESYS, a platform widely used in industry for programming PLCs (Programmable Logic Controllers). The expected results include demonstrating the usefulness of PID in ensuring stability and reducing overshoot in level control, as well as validating the system's response to disturbances and instabilities. The combination of Simmaq 3D and CODESYS allows for replicating industrial scenarios and provides a safe environment for iterative testing.
