Bancada didática para controle de nível e temperatura

Abstract

This paper proposes the construction of a didactic bench to serve as a teaching tool in classes of supervisory control and control of linear systems. Through the countertop is possible to implement systems for level and temperature control, aiming to bring to students real problems. To provide the operation of these systems are used various devices and equipment such as programmable logic controller (PLC) and level,temperature, and flow sensors. The level is controlled by a centrifugal pump, and temperature control is performed by an electric boiler. Thus, it was necessary to study the behavior of all materials involved in the assembly and system implementation. After building the didactic bench were modeled the level and temperature systems that enabled the implementation of its PI controllers, which in addition to having a good performance contributed to demonstrate the operation of the bench. Finally, all the performance of the bench can be observed by a supervisor system which serves to monitor the changes of the variables of outputs also allow the modification of parameters and variables of the plant.
