Modeling of a MIT for the application of a frequency inverter of the electric vehicle
(2011-12-01)
Nowadays, drives that use a combination of induction motors and frequency inverters are very common, a fact due to the financial practicality and viability in purchasing and operating that system. This system modeling and ...
Modelling of the influence of the layer pollution thickness in high voltage polluted insulators
(1995-12-01)
An experimental model and a mathematical model with the introduction of a ramp in the channel of Obenaus model are presented. The aim is to present a better reproduction of the real layer pollution deposited on the HV ...
Water waves generated by local disturbance: Serre's model validity
(2002-12-01)
Water waves generated by landslides were long menace in certain localities and the study of this phenomenon were carried out at an accelerated rate in the last decades. Nevertheless, the phase of wave creation was found ...
On non-linear and non-ideal interactions in two vibrating problems
(2008-06-17)
In practical situations, the dynamics of the forcing function on a vibrating system cannot be considered as given a priori, and it must be taken as a consequence of the dynamics of the whole system. In other words, the ...
The accuracy potential of Galileo E5/E1 pseudoranges for surveying and mapping
(2011-12-01)
In the paper we discuss the potential of the new Galileo signals for pseudorange based surveying and mapping in open areas under optimal reception conditions (open sky scenarios) and suboptimal ones (multipath created by ...
A comparative study between two relaxed LMI-based fuzzy control designs
(2005-09-01)
A comparative study, with theoretical analysis and digital simulations, of two conditions based on LMI for the quadratic stability of nonlinear continuous-time dynamic systems, described by Takagi-Sugeno fuzzy models, are ...
On designing linearly tunable high-Q OTA-C filters with low sensitivity
(2004-09-07)
This paper discusses a design approach for a high-Q low-sensitivity OTA-C biquad bandpass section. An optimal relationship is established between transconductances defining the differenceβ - γ in the Q-factor denominator, ...
Generating VHDL-AMS models of digital-to-analogue converters from MATLAB®/SIMULINK®
(2007-11-27)
Today, the trend within the electronics industry is for the use of rapid and advanced simulation methodologies in association with synthesis toolsets. This paper presents an approach developed to support mixed-signal circuit ...
A radial basis function network (RBFN) for function approximation
(IEEE, 1999-01-01)
A radial basis function network (RBFN) circuit for function approximation is presented. Simulation and experimental results show that the network has good approximation capabilities. The RBFN was a squared hyperbolic secant ...
On numerical simulations of a nonlinear self-excited system with two non-ideal sources
(2005-12-01)
In this work, the dynamic behavior of self-synchronization and synchronization through mechanical interactions between the nonlinear self-excited oscillating system and two non-ideal sources are examined by numerical ...
