13. Propostas de metodologias para identificação e controle inteligentes / Proposals of methodologies for intelligent identification and control
This thesis presents proposals of methodologies for intelligent identification and control. A methodology for nonlinear dynamic discrete time systems identification, based on the instrumental variable method and Takagi-Sugeno fuzzy model, is presented. In this methodology, which is an extension of the standard instrumental variable method, the chosen instrum

14. Sistema neural hÃbrido para reconhecimento de padrÃes em um nariz artificial / Hybrid neural system forpattern recognition in an artificial nose
This dissertation investigates the use of Hybrid Intelligent Systems in the pattern recognition system of an artificial nose. The work involves five main parts: (1) an evaluation of the odors database by a multivariate statistics technique; (2) a validation of the Time Delay Neural Networks in the odors recognition; (3) an evaluation of the Wavelet Transform

15. Redes neurais aplicadas em estrategias de controle não linear
The artificial neural networks are computational tools with a great number of applications in modeling techniques and process control. Such fact is due its capacity to learn sufficiently accurate models and give good nonlinear control when model equations are not known or only partial state information is available. Neural network approach allows taking into

16. ONLINE TRAINING OF NEURAL METWORKS: METHODOLOGY FOR TIME VARYING ENVIRONMENTS / TREINAMENTO CONTÍNUO EM REDES NEURAIS: UM TRATAMENTO PARA AMBIENTES VARIANTES NO TEMPO
The main issue when dealing with non-stationary processes is related to the requirement of fast adaptation while simultaneously preventing catastrophic damage to previously learned behavior. In this thesis, two on-line learning techniques, one for supervised and the other for unsupervised artificial neural networks, are proposed. A new supervised procedure t

17. Redes neurais artificiais para o controle da mancha produzida por estimilação eletrica neuromuscular
This work consisted in the application of artificial neural network algorithms for control of gait generated by NeuroMuscular Electrical Stimulation (EENM) in spinal cord injured subjects. Two independent approaches were attempted -namely, a theoretical, and an experimental approach. ln the theoretical study, a three-Iayered neural network was set up to mode
