SISTEMA ELECTRÓNICO PARA EL CONTROL DE MOVIMIENTO DE UN SEGUIDOR SOLAR (ELECTRONIC SYSTEM FOR CONTROL POSITION OF A SOLAR TRACKER)
Resumen
Un tipo particular de seguidor solar es el de dos grados de libertad en donde el dispositivo de captación, el concentrado solar, se posiciona activamente sobre la trayectoria solar conforme dos ángulos conocidos como altitud y azimut. En este trabajo se presenta el sistema electrónico desarrollado para un seguidor solar activo de dos grados de libertad para mover un concentrado solar con peso aproximado de 1000 kg. El sistema electrónico está construido con herramientas básicas de desarrollo con el objetivo de no depender de licenciamientos. El sistema electrónico controla dos motores a paso de alta corriente que generan los ángulos de altitud y azimut mediante el cálculo de las ecuaciones solares. Además, el sistema electrónico cuenta con conectividad al internet de las cosas. Se incluye un microcontrolador Arduino con algoritmos específicos para el control y comunicaciones. El sistema electrónico se encuentra en la etapa de depuración y posteriormente se integrará a los prototipos de concertadores solares finales.

Abstract
A particular type of solar tracker is the two degrees of freedom where the capture device is actively positioned on the solar path according to two angles known as altitude and azimuth. This paper presents the electronic system developed for an active solar tracker of two degrees of freedom for moving a solar concentrator with a weight of approximately one ton. The electronic system is built with basic development tools in order not to depend on licensing. The electronic system controls two high-current stepping motors that generate the altitude and azimuth angles by calculating the solar equations. In addition, the electronic system has connectivity to the Internet of Things. An Arduino microcontroller with specific algorithms for control and communications is included. The electronic system is in the debugging stage and will later be integrated into the final prototypes of solar concentrators.
Keywords: Arduino microcontroller, Internet of Things, Solar tracker.
