Construção de uma planta de nível monotanque, de baixo custo, para estudo de modelagem e controle de processos

Abstract

This article describes the design and development of a mono-tank level plant to aid in teaching process control, systems identification, controller design. The use of accessible and low-cost materials allows other students to build their plant, also allowing the development of practical skills, relevant to the training of an engineer. In the context of control theory, level processes are found in different types of industry, such as petrochemicals, water distribution, chemicals, boilers, among others. Therefore, it becomes relevant to enable and encourage practical activities in the industrial processes area, providing the practical application of the concepts of process identification and control. The work presents the materials and points taken into account in the development of the real plant, as well as presents some of the identification and control techniques that can be applied to the plant, such as: classic identification techniques, PID (Proportional, Integral, Derivative) and GMV (Generalized Minimum Variance)-PID controllers.
