Some Rezults Concerning No-Storage Wide-Diesel Systems Control
("Dunarea de Jos" University of Galati, 2006)
This paper deal with the dynamics of an autonomous no storage wind-diesel system, comprising a diesel generator and a controlled wind system with a hypo/hyper synchronous cascade. The objective is to maximize the wind ...
Stationary Frame Active Power Filter Control Based on Multiresolution Analysis
("Dunarea de Jos" University of Galati, 2006)
The paper presents an active power filter control method. The reference signal
is generated in the stationary reference frame α-β using multiresolution analysis and the
controllers used are P-resonant controllers, suitable ...
Aspects Regarding the Neuro-Adaptive Control Structura Proprieties. Application to the Nonline Pneumatic Servo System Benchmark
("Dunarea de Jos" Universsity of Galati, 2006)
Generally, control techniques based on multilayer neural networks are used especially in the case of non-linear process and less in case of linear process, because classical control techniques are good enough and relatively ...
Non-Conventional Method for Friction Compensation in DC Drive Position Tracking
("Dunarea de Jos" University of Galati, 2006)
Friction, especially its nonlinear components, may degrade the tracking
performance of any servo drive systems. Focused on high precision positioning of DC
electrical drive the paper proposes an easy method to compensate ...
Indirect Control of a Single-Phase Active Power Filter
("Dunarea de Jos" University of Galati, 2006)
The control of shunt active power filters using PWM inverters consists in generating a reference by separating, using different methods, the harmonics to be eliminated. The methods used are time-consuming and need dedicated ...
Power Conditioning System Topology For Grid Integration of Wind and Fuel Cell Energy
("Dunarea de Jos" University of Galati, 2006)
This paper shows the topology of the hybrid grid-connected power system and the performances of the front-end three-phase power inverter. The renewable sources of the hybrid power system consist of a solid oxide fuel cell ...
The Influence of Non-Homogenous Dielectric Material in the Waveguide Propagation Modes
("Dunarea de Jos" University of Galati, 2006)
The aim of this paper is to indicate the equations of electromagnetic wave in homogenous and non-homogenous dielectric material, estabilising the bundary conditions and solves by FEM the equations of the electromagnetic ...
A Novel Feature Extraction Method for Isolated Word Recognition Based on Nested Temporal Averaging
("Dunarea de Jos" University of Galati, 2006)
A novel preprocessing method is proposed. It has a reduced complexity and therefore is aimed to be used in low power, VLSI implemented, speech recognizers. Our algorithm extracts a feature vector made from up to 3 feature ...
Sonar Target Localization Based on Spike Coded Spectrograms
("Dunarea de Jos" University of Galati, 2006)
Target location is coded into the pattern of spikes that run up the auditory nerve to the bat's brain. Realistic scenes containing multiple, closely spaced, reflectors give rise to complex echo signals consisting of multiple ...
Minimizing the Error Tracking of Mobile Terminals by Kalman Filtering
(2006)
A method to track mobile terminals in a cellular communication network is presented. It uses the received field strength from the surrounding base stations. A subsequent Kalman filtering is used to minimize the tracking error.
