Analysis and Control of Chaotic DC-DC Switching Power Converters
(Sin editorial (Orlando, Estados Unidos de América), 2002-08-06)In this paper we review our approach to computing the static characteristics-such as voltage gain and average switching frequency-of open loop DC-DC converters under current-mode control in the chaotic regime. Linearized ... -
On-line estimation of the stator parameters in an induction motor using only voltage and current measurements
(Sin editorial (Phoenix, Estados Unidos de América), 2002-08-06)This paper proposes a set of algorithms for stator parameter on-line estimation (stator resistance, stator inductance and leakage inductance) of a induction motor using neither the rotor speed nor the rotor resistance. The ... -
Model-based loss minimization for DC and AC vector controlled motors including core saturation
(Sin editorial (Phoenix, Estados Unidos de América), 2002-08-06)A generalised d-q loss model for electrical motors is presented in this paper. It is shown to be applicable to permanent magnet synchronous motors, reluctance synchronous motors, induction motors and DC motors. A model-based ... -
Application of the OGY method to the control of Chaotic DC-DC Converters: Theory and Experiments
(Sin editorial (Ginebra, Suiza), 2000-08-06)In this paper we implement OGY's method to control the chaotic behavior of a boost DC-DC converter under current mode control. In this approach the samples of the inductor current of the actual boost converter follow a ... -
Thermoelectricity applied to heating of a fuel filter of a car in a cold starting
(Sin editorial (Cardiff, Reino Unido), 2000-08-24)This paper presents the results of an investigation about the use of thermoelectricity in a car fuel filter in order to prevent the problems associated to its obstruction due to the creation of paraffins when the car is ... -
Bidimensional analysis of a themoelectric module using finite element techniques
(Sin editorial (Cardiff, Reino Unido), 2000-08-24)In this paper an analysis is performed on a thermoelectric module using finite element techniques taking into account the following two hypothesis: thermal and electrical flows are present in two dimensions. -

Frequency response of a magnetooptic sensor using magnetic pulses
(International Measurement Confederation (Lisboa, Portugal), 2015-08-01)The great advantage of using thin cobalt films as magnetooptic material in sensors to measure currents or magnetic fields is its wide bandwidth because it can reach the magnitude of several GHz. Though this fact is widely ... -
Rheed signal sampling device
(International Measurement Confederation (Lisboa, Portugal), 2015-08-01)Monitoring the intensity of the reflected spot in a RHEED image is the most important method used to control the growth of semiconductor crystals in facilities like for example MBE. In some application the availability of ... -
EMI Measurements in line-pantograph contact discontinuity railway transportation systems
(International Measurement Confederation (Lisboa, Portugal), 2015-08-01)In this paper the results of a measurement campaign aimed at investigating electromagnetic emissions in sliding contacts are presented. Different experimental setups have been used for the investigation and, in particular, ... -
Modelado de un entorno de navegación desconocido por un vehículo autoguiado mediante una red neuronal adaptativa
(Sin editorial (Gijón, España), 2001-11-16)En este artículo se describe una forma de modelar el entorno cuando éste es desconocido. Para ello se propone el uso de un modelo de ocupación de obstáculos. El modelo de ocupación se encarga de modelar la incertidumbre ... -
An overview of an AGC for a de-regulated power system
