Controle ótimo H∞ de sistemas não-lineares com modelos fuzzy takagi-sugeno

Abstract: A design method for tracking system with disturbance rejection applied to nonlinear systems using fuzzy control is proposed in this paper. Fuzzy feedforward controllers M (α) and N (α) are designed in order to obtain the tracking system. These controllers minimize the H ∞ -norm from the reference input signal r(t) to the tracking error signal e(t), where the tracking error signal is the difference between the reference input signal r(t) and the output signal z(t). A dynamic feedback fuzzy controller K c (α) is… Show more

“…Do ponto de vista prático, diversas aplicações têm sido reportadas na literatura e, em particular, a utilização da modelagem fuzzy de Takagi-Sugeno (Wang et al, 1996) apresenta-se como umaárea interessante para a aplicação de técnicas de controle LPV e, também, para o desenvolvimento de novos resultados teóricos (p.ex. : Guerra and Vermeiren, 2004;Khiar et al, 2007;Andrea et al, 2008;Tognetti et al, 2009;Montagner et al, 2010;Zheng et al, 2001;Zhou et al, 2007). Na representação fuzzy de Takagi-Sugeno (T-S) o parâmetro variante consiste em funções peso normalizadas, geralmente dependente dos estados do sistema, que controlam a interpolação entre os modelos locais (regras).…”
