1. Use of a combined SVD-Kalman filter approach for induction motor broken rotor bars identification
Abstract This paper describes a new parametric spectral estimator for the identification of rotor bar fault of an induction motor by analyzing the stator current. This approach combines two methods: The first one, the Singular Value Decomposition method which allows the accurate detection and location of the fault's signature frequency. The second method all

2. Detecção de falhas em circuitos eletrônicos lineares baseados em classificadores de classe única. / Fault detection in electronics linear circuits based in one class classifiers.
This work deals with the application of one class classifiers in fault detection. The faults to be detected are related parametric faults. The transfer function of each circuit was generated and the outputs signals with the components in and out of tolerance were analyzed. Pattern recognition and one class classifications tools are employed to perform the an

3. A melhoria da disponibilidade do compensador estÃtico da SE FTZ/CHESF atravÃs da anÃlise da sua Ãrvore de falhas
In the Electrical Power Systems, the Static Compensators â CE are equipment of extreme importance for tension regulation, both in a permanent regime as in a transitory one, mainly in systems where the load centers are located at great distances of the generating plant. This dissertation presents an analysis of the fault causes in the Static Compensator inst

4. Nonlinear H INFINITO control of underactuated robot manipulators / Controle H INFINITO não linear de robôs manipuladores subatuados
This work presents the development, implementation and analysis of nonlinear H control techniques applied to underactuated manipulators, under parametric uncertainties and external disturbances. At the first part, two approaches are considered for underactuated individual manipulators. The first approach consists in representing manipulators as nonlinear
