Brushless doubly fed induction machine as a variable frequency transformer
(
IEEE
, 2012 , Conference Paper)
Variable frequency transformer (VFT) has been recently used as an alternative to HVDC to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster ...
A modified modulation scheme for capacitor voltage control of renewable energy-fed grid-connected Z-Source Inverters
(
IEEE
, 2012 , Conference Paper)
An important issue in grid connection applications is boosting the limited output voltage of the renewable energy sources. Two-stage converters are most commonly employed for successful grid connection and optimum power ...
Single sensor three-phase permanent magnet synchronous motor drive based on Luenberger style-observers
(
IEEE
, 2012 , Conference Paper)
This paper presents a technique to estimate phase currents and rotor position in a vector-controlled PMSM drive using only dc-link current measurement. Three cascaded Luenberger style observers were used to perform this ...
Magnetic gearbox with an electric power output port and fixed speed ratio for wind energy applications
(
IEEE
, 2012 , Conference Paper)
Mechanical gearboxes are typically employed with doubly-fed induction generator-based wind turbines. The main drawback of this solution is the gearbox's reliability and maintenance. Using magnetic gearbox in conjunction ...
A coaxial magnetic gearbox with magnetic levitation capabilities
(
IEEEIEEE
, 2012 , Conference Paper)
Magnetic gearboxes (MGBs) are now a powerful alternative to their conventional mechanical counterparts in terms of reduced maintenance requirements, improved reliability, tolerance to mechanical inaccuracies, and inherent ...
Control of doubly-fed induction machine storage system for constant charging/discharging grid power using artificial neural network
(
IET
, 2012 , Conference Paper)
A large-capacity low-speed flywheel energy storage system based on a doubly-fed induction machine (DFIM) basically consists of a wound-rotor induction machine, and a back-to-back converter for rotor excitation. It has been ...
Wavelet-based multiscale filtering of genomic data
(
IEEE Computer Society
, 2012 , Conference Paper)
Measured biological data are a rich source of information about the biological phenomena they represent. For example, time-series genomic or metabolic microarray data can be used to construct dynamic genetic regulatory ...
Multiple sensor fault diagnosis for non-linear and dynamic system by evolving approach
(
2012 3rd Annual IEEE Prognostics and System Health Management Conference, PHM-2012
, 2012 , Conference Paper)
Reliability of sensor measurement is vital to assure the performance of complex and nonlinear industrial operation. In this paper, the problem of designing and development of a data-driven multiple sensor fault detection ...
Output-feedback model predictive control of biological phenomena modeled by S-systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2012 , Conference Paper)
Recent years have witnessed extensive research activity in modeling biological phenomena as well as in developing intervention strategies for them. S-systems, which offer a good compromise between accuracy and mathematical ...
Evidence theory-based approach for epileptic seizure detection using EEG signals
(
IEEE
, 2012 , Conference Paper)
Electroencephalogram (EEG) is one of the potential physiological signals used for detecting epileptic seizure. Discriminant features, representing different brain conditions, are often extracted for diagnosis purposes. ...
