Acionamento de um Sistema de Rastreamento Solar Real em Malha Fechada Utilizando FPGA

Abstract

The present work aims to propose the development of a real solar tracking system using an FPGA (Field Programmable Gate Array) for control, and together with the development of all interfaces and drivers connected to the electronics involved for the correct functioning of the components. The module in question is a set of 6 solar panels in series, supported on a single axis support. The movement of the plates will be carried out by a DC motor that will be attached to the structure that it supports. Thus, the aim is to develop the control system for the motor activation in closed loop using MATLAB/Simulink associated with the FPGA as an auxiliary platform. Finally, it is verified the closed loop operation, simulating the behavior of the DC motor by an RL load, performing the activation of the system in the positive and negative direction, obtaining in the end a similar response between the simulation and the real system.
