Modelagem e implementação de controle de nível em sistemas de tanques

Abstract

The purpose of this paper was the study of modeling methods and implementation of a PID controller in a water-level tank system. The plant was composed by two tanks, a hydraulic pump, and an ultrasonic sensor. Arduino microcontrollers were used to stablish the communication Plant/Scilab-Xcos with the objective of monitoring the water level signal, as well as transmitting control actions to be executed. After building the system and implementing the PID controller, the tests demonstrated a quick response of the controller to applied disturbances, keeping the system in stability. Even though the methodology as shown good results, new tests, with different kinds of sensors and controlling design techniques should be performed in the pursue of better results in the process control.
