RESUMO:

In this work a process of adjustment of PID  controllers using the auto tuning method oriented to the robustness of the system and implemented in a Programmable Logic Controller (PLC) with the use of relay experiments is presented, with possibility of application in PI-D controllers. The method was developed through the adaptation of methods directed to existing PI controllers, with the objective of using few iterative structures, allowing the implementation in PLC, as well as improving the performance in the transient response of the system. Robustness is indicated by the maximum sensitivity of the system. Relay experiments provide frequency response points that allow calculation of parameters that modify the original terms of the controller in order to remove the points from the interior of the maximum sensitivity circle. Results of two PLC applications of different didactic systems allowed comparison with an existing PI controller tuning method and the demonstration of the effectiveness of the method.
