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 ...
Possibilistic Networks for Uncertainy Knowledge Processing in Student Diagnosis
("Dunarea de Jos" University of Galati, 2006)
In this paper, a possibilistic network implementation for uncertain knowledge modeling of the diagnostic process is proposed as a means to achieve student diagnosis in intelligent tutoring system. This approach is proposed ...
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 ...
Identification of the Non-Linear Systems Using Internal Recurrent Neural Networks
("Dunarea de Jos" University of Galati, 2006)
In the past years utilization of neural networks took a distinct ampleness because of the following properties: distributed representation of information, capacity of generalization in case of uncontained situation in ...
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 ...
Proton Exchange Membrane Fuel Cell Modelling Using Moving Least Squares Technique
("Dunarea de Jos", 2009)
Proton exchange membrane fuel cell, with low polluting emissions, is a great
alternative to replace the traditional electrical power sources for automotive applications
or for small stationary consumers. This paper ...
Spatio-Temporal Dynamics in Celular Neural Networks
("Dunarea de Jos" University of Galaţi, 2009)
Analog Parallel Architectures like Cellular Neural Networks (CNN’s) have
been thoroughly studied not only for their potential in high-speed image processing
applications but also for their rich and exciting spatio-temporal ...
Learning Bayesian Dependence Model for Student Modelling
("Dunarea de Jos" University of Galati, 2008)
Learning a Bayesian network from a numeric set of data is a challenging
task because of dual nature of learning process: initial need to learn network
structure, and then to find out the distribution probability tables. ...
