Adaptive Control for Solar Photovoltaic Tracking System

Abstract:

This paper describes the behavior of adaptive control using the MIT rule for a polar aligned single axis tracking system, it´s for increase the efficiency of solar energy capturing compared to a polar fixed system, where the response of system is analyzed by simulation in Simulink – MATLAB® software. The data input for estimate the energy in the photovoltaic panels is the radiation data, that is obtained by weather station of the CAR (regional autonomous corporation) situated in the zone of study. The objective of the integration between the photovoltaic panel and the mechanics tracking system is to keep the perpendicular sunlight during the day. The MIT adaptive control tries to reduce possible errors, such a sun position data deviations, friction and environmental changes in the conventional solar tracking. This control was designed according to a typical polar aligned single axis tracker.
