AMBIENTE PARA SIMULAÇÃO E APLICAÇÃO NUMA PLANTA DIDÁTICA DE UM CONTROLADOR PID COM ANTI WIN-UP

The teaching of classical control is usually done through pre-programmed controllers, where the user only inserts the tuning parameters. Although this practice is usual in the industrial environment, in an academic environment, it is necessary that students can develop their own control algorithms quickly and efficiently, bringing security of the knowledge acquired. This article presents examples of simulation and practical application of the PID controller that can serve as a guide for teaching the subjects of control. A data acquisition board was used to access the variables of a didactic plant. A graphical programming software (LabVIEW) was used to implement the PID controller, using for this the difference equation obtained by discretization, thus reducing the distance between theoretical learning and practical.
