Diseño y desarrollo de un sistema de posicionamiento automático seguidor de la luz solar de un eje , controlado por medio de un microcontrolador y un motor paso a paso como actuador, empleando un control con lógica difusa

Abstract

Solar energy is the energy obtained from the use of electromagnetic radiation from the sun. Solar radiation reaching the Earth has been harnessed by humans since ancient times, using different technologies that have evolved over time from conception. Currently, heat and sunlight can be exploited by collectors and photovoltaic cells, heliostats or thermal collectors, which can transform into electrical or thermal energy. It is a so-called renewable energy and clean energy, which can make significant contributions to solving some of the most pressing problems facing humanity. Moreover the use of fuzzy logic in this project is important because inaccurate data will be used, and fuzzy logic function is to work as closely equal the human brain. Fuzzy logic is oriented to present answers to problems in very complex processes where simple mathematical models do not have the capacity to develop them. For this project a system that allows control of brightness depending on the orientation of the sun, a method of artificial intelligence endowed with maximum precision captures solar radiation and its impact to be exploited develop. That is why the need to develop a project where an implementation of an automatic positioning follower of sunlight, controlled by a microcontroller using fuzzy logic control is performed.
