ABSTRACT: Photovoltaic solar panels, and those for heating water, achieve maximum performance when the sun's rays fall perpendicular to their surface. For this reason, electromechanical systems have been created that enable tracking the position of the sun through proportional control, which functions based on the signal received from the sensor, but with a significant error value. These types of systems tend to oscillate around the specified position with a certain amount of error in position and time, reducing the performance from the maximum values. Keeping these processes in a sustainable state is another challenge for the designer. This article will analyze a positioning panel process, will build the mathematical model of the system and based on this mathematical model will program a highprecision Proportional-Integral-Derivative control, which will be able to keep the position of the panel at the desired point. The article also aims to highlight the difference between the traditional feedback control system methods such as the proportional system and the PID system. For the implementation of this control, we will use a programming language such as LabView.
