Previous issue date: 2013-09-13 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / In the last decade, the renewable energy sources have present a major propulsion in
the world due to several factors: political, environmental, financial and others. Within this
context, we have in particular the energy obtained through wind, wind energy - that has
highlighted with rapid growth in recent years, including in Brazil, mostly in the Northeast,
due to it s benefit-cost between the clean energies. In this context, we propose to compare
the variable structure adaptive pole placement control (VS-APPC) with a traditional
control technique proportional integral controller (PI), applied to set the control of machine
side in a conversion system using a wind generator based on Double-Fed Induction
Generator (DFIG). Robustness and performance tests were carried out to the uncertainties
of the internal parameters of the machine and variations of speed reference. / As fontes de energia renov?veis t?m, na ?ltima d?cada, ganho uma grande propuls?o
em todo o mundo devido aos mais diversos fatores: pol?ticos, ambientais, financeiros, entre
outros. Dentro deste universo, temos, em especial, a energia obtida atrav?s do vento,
energia e?lica - que tem se destacado com um crescimento vertiginoso nos ?ltimos anos,
inclusive no Brasil, principalmente na regi?o Nordeste, devido ao seu custo-benef?cio
entre as energias "limpas". Neste cen?rio, prop?e-se a compara??o do controlador por
posicionamento de polos e estrutura vari?vel (VS-APPC) com o controlador proporcional
integral (PI) aplicados em um sistema de convers?o de energia e?lica que utiliza um gerador
de indu??o duplamente alimentado (Double-Fed Induction Generator- DFIG). Testes
de robustez e desempenho foram realizados com incertezas nos par?metros da m?quina e
varia??es de refer?ncia de velocidade
