Controle com adaptação em modo dual utilizando uma rede RBF

This work presents a control strategy using a network with radial basis function (RBF network) with adaptation in dual mode. The objective of the strategy is to use the approximate capacity of the RBF network to control nonlinear systems with unknown parameters or with uncertainties. The proposed control uses the structure of Model Reference Adaptive Control (MRAC) and a RBF network whose param...

O espectro de uma terceira onda: questões e desafios da educação formal em IHC em uma instituição brasileira

We present in this article some reflections on the challenges of developing an HCI education aligned on the so called HCI third wave. We discuss the necessary perspective of such an endeavor in order to ground a curriculum reformulation under development at UTFPR, Curitiba. We address the tensions between the established curricula recommendations from one side, and the cultural, axiological, po...

Controle Com Adaptação Em Modo Dual Utilizando Uma Rede De Gaussianas

In this paper, a RBF network with Gaussians is adapted through a combination of switching and integral laws. The idea is to take the best features of each method. The hyperbolic tangent is used instead of signal function what reduces the chattering phenomenon. A hyperbolic secant is used to intercalate the methodologies, yielding a dual mode that results on zero error in steady state and a smoo...
