“…Intelligent control, on the other hand, has proven to be a very attractive approach to cope with uncertain nonlinear systems [2]- [6], [9], [15], [16], [23]. By combining nonlinear control techniques, such as feedback linearization or sliding modes, with adaptive intelligent algorithms, for example fuzzy logic or artificial neural networks, the resulting intelligent control strategies can deal with the nonlinear characteristics as well as with modeling imprecisions and external disturbances that can arise.…”

“…Para o GPR, foi considerado como entrada os estados x = [xẋẍ] e a média a priori nula (µ(s) = 0). Como adotado por Lima et al (2018), foi utilizado como função de covariância o kernel da Função de Fase Radial (RBF, do inglês Radial Basis Function) também chamada de exponencial quadrática, definida abaixo:…”

O processo de aprendizagem por GPR consiste em, dado um conjunto de treinamento Lima et al (2018) e Doerr et al (2018) sugerem que tanto a média quanto a variância a posteriori sejam calculadas com base nas seguintes equações:…”

“…Contudo, ao invés dessa estratégia de treinamento, utilizamos o método de janela deslizante que permite o compensador aprender gradualmente com o ambiente. Essa estratégia já tem sido utilizada para sistemas atuados no caso do controle de posicionamento de um veículo subaquático Lima et al (2018Lima et al ( , 2020.…”
