  • SANTOS, Carlos Eduardo dos (Universidade Federal de ItajubáBrasilIESTI - Instituto de Engenharia de Sistemas e Tecnologia da InformaçãoPrograma de Pós-Graduação: Mestrado - Engenharia ElétricaUNIFEI, 2007-12-14)
    A fundamental procedure to guarantee the energy quality in electric systems is the tension regulation. However, it is not a trivial activity due to the great number of state variations that an electric system is ...
  • MARTINS, Leandro Chiavegatto (Universidade Federal de ItajubáBrasilIESTI - Instituto de Engenharia de Sistemas e Tecnologia da InformaçãoPrograma de Pós-Graduação: Mestrado - Engenharia ElétricaUNIFEI, 2004-09-03)
    This work proposes the use of sliding mode control applied in voltage regulation of synchronous machine working as generator. The main aspects of variable structure control (VSC) using sliding mode are presented. The ...

    Until a few decades, control systems for induction engines (totally more robust than the other kind of engines) were more costly when compared with the control of motors of continuous current. With the advent of theory ...
  • RIBEIRO, Ricardo (Universidade Federal de ItajubáBrasilIESTI - Instituto de Engenharia de Sistemas e Tecnologia da InformaçãoPrograma de Pós-Graduação: Mestrado - Engenharia ElétricaUNIFEI, 2007-04-09)
    The use of automatic control systems is found to be fully spread out through our daily use in all the developed societies. Such systems work as catalyzing elements to promote the progress and development. The example ...
  • FERREIRA, Helenice Cristina; http://lattes.cnpq.br/5932907963935118 (Universidade Federal de ItajubáBrasilIESTI - Instituto de Engenharia de Sistemas e Tecnologia da InformaçãoPrograma de Pós-Graduação: Mestrado - Engenharia ElétricaUNIFEI, 2006-06-30)
    This work has as goal to implement a simple and efficient system that enables to make experiments in control loops from afar using data communications resources, like the Internet. The proposal consists in the ...
  • ANTUNES, Flávia (Universidade Federal de ItajubáBrasilIESTI - Instituto de Engenharia de Sistemas e Tecnologia da InformaçãoPrograma de Pós-Graduação: Mestrado - Engenharia ElétricaUNIFEI, 2007-05-23)
    In the last few years, the growth of the academic production about non-linear dynamic systems was noticed. Although the researches evolved, there are still topics that deserve a close analysis. One of them includes the ...
