Previous issue date: 2014-01-23 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The use of solar energy for electricity generation has shown a growing
interest in recent years. Generally, the conversion of solar energy into electricity is made
by PV modules installed on fixed structures, with slope determined by the latitude of
the installation site. In this sense, the use of mobile structures with solar tracking, has
enabled increased production of the generated energy. However, the performance of these
structures depends on the type of tracker and the position control used. In this work, it is
proposed position control a strategy applied for a solar tracker, which will be installed in
Laboratory of Power Electronics and Renewable Energy (LEPER), located in the Federal
University of Rio Grande do Norte (UFRN). The tracker system is of polar type with daily
positioning east-west and tilt angle manual adjustment in the seasonal periods, from north
to south / O aproveitamento da energia solar para gera??o de energia el?trica tem apresentado
um crescente interesse nos ?ltimos anos. Geralmente nestes sistemas, a convers?o de
energia solar em el?trica ? realizada por m?dulos fotovoltaicos, instalados em estruturas
fixas, com inclina??o determinada em fun??o da latitude do local de instala??o. Neste
sentido, o uso de estruturas m?veis, com rastreamento solar, tem possibilitado o incremento
da produ??o da energia gerada. Por?m, o desempenho dessas estruturas depende
do tipo de rastreador instalado e do tipo de controle de posi??o utilizado. Nesta disserta??o,
? empregada uma estrat?gia de controle de posi??o aplicada a um rastreador solar,
que ser? instalado no Laborat?rio de Eletr?nica de Pot?ncia e Energias Renov?veis (LEPER),
localizado na Universidade Federal do Rio Grande do Norte (UFRN). O rastreador
ser? do tipo polar, com rastreamento di?rio no sentido leste-oeste e ajuste do ?ngulo de
inclina??o manual nos per?odos sazonais, no sentido norte-sul
