Abstract

Solar panels have problems in terms of the optimal capture of solar energy, reducing their efficiency due to the static position they maintain throughout the year. This article presents the proposal for the development of a fuzzy control to position a mechanical structure, which supports a solar panel seeking to obtain maximum capture in solar farms. The fuzzy control law defines rules that together cause a nonlinear control law by evaluating the performance of the controller through graphics and its simulation in the MatLab Simulink® software. The mechanical structure used has an arrangement of photoresistors at the ends of the surface, which determined the desired elevation angle, generating the control setpoint. Three experiments were developed to validate the operation of the resulting controller, concluding that the diffuse system decreases the position error with respect to the incidence of solar radiation on the photovoltaic cells and the rotational movement of the Earth.
