Construção e testes em um módulo experimental de um sistema de dois tanques sem interação

Abstract

This paper presents the modeling and control of a low-cost experimental module for a laboratory of process control. The plant is a two tanks coupled system with the systems control being done via a DAQ. The modeling was done approximating the system as a first-order one, then, determining the black box and white box models. Also, the process was done varying parameters in the system to compare the resulting poles, which was done changing the orifice in the tank being modeled. After, PI controllers were designed to control the plant, tests were done for different set points and the results analyzed using an algorithm. The script made determined the overshoot and settling time for each run and compared them graphically. Finally, it was determined the effect of each modeling in the resulting controller response.
