The automatic setting of the control system parameters contains algorithms and recommendations to select the coefficient size, which ensures the desired system response to disturbance or setpoint change of the target value. We carried out two separate experiments. In both experiments, the systems were controlled using the Arduino platform. The first experiment was performed on a DC-motor and the other on a mobile robot. The measurements were made in a closed-loop system, where we measured the amplitude of the oscillation and its frequency. We have found that, in ideal circumstances, the Ziegler-Nichols recommendations apply and that they ensure a rapid response of the system.
