RESUMO:

Automatic process control is a growing demand in industries that seek techniques that automate the parameterization of control systems and ensure efficiency, quality and safety. This work aims to implement a method of assessment and readjustment of PI controllers, for the system to achieve robust performance and stability in the presence of disturbances. The method is inspired by works from the literature and has two stages, the first step is to evaluate the robustness of the controller, in which its gain and phase margins are estimated. And if the robustness parameters are violated or not reached, in the second step the parameters of the PI controller will be corrected. It’s intended to program the method directly into a PLC to work together with its controller. Initially, the results are evaluated by computational simulations of the method so that it’s later passed to PLC. The experiments will be performed in real processes controlled by PLC to support the simulated results.
