Open-Loop control of a Bipolar Stepper Motors Using the Specialized Integrated Circuits
("Dunarea de Jos" University of Galati, 2004)
The paper describes the open-loop control of a stepper motors. Bipolar stepper motors can be driven with an L297, an L298N bridge driver and very few external components. With an L298N this configuration drives motors with ...
Modeling, Identification and simulation of a Lighting Control System
("Dunarea de Jos" University of Galati, 2002)
This paper presents the results of the first phase in the design of a control
system for closed-loop regulation of the light amount in office-building rooms. This
project is a joint development of Ghent University and ...
A New Method of Gene Coding for Genetic Algorithm Designed for Parametric Optimization
("Dunarea de Jos" University of Galati, 2003)
In a parametric optimization problem the genes code the real parameters of the
fitness function. There are two coding techniques known under the names of: binary
coded genes and real coded genes. The comparison between ...
Considerations on the Effect of Plastic Deformation Over the Magnetic Behavior of Soft Ferromagnetic alloy FE-3%SI NO
(2002)
The paper synthetically presents the results obtained over the degradation of
magnetic properties of soft ferromagnetic sheets Fe-3%Si NO required mechanically in
plastic deformation area. Chronologically, the evolution ...
On the Performances of Different types of Controllers for Active Power Filters
("Dunarea de Jos" University of Galati, 2004)
This paper analyses the performances of three different types of controllers for shunt active power filters. The controllers are used in the d-q frame, the same frame in which the reference signal for the 5th and 7th ...
The Influence of the Ship's Steering Machine Over Yan and Roll Motions
("Dunarea de Jos" University of Galati, 2003)
The steering machine is a nonlinear system, with two important limitations:
the maximum rudder angle and rudder rate. Therefore, the commands from yaw and
rudder-roll control systems are modified and the expected effect ...
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. ...
Pid Self-Tuning Controllers Used in Different Structures of the Control Loops
("Dunarea de Jos" University of Galati, 2008)
The paper investigates the behavior of digital PID self-tuning controllers
(STC) in different structures of the control loops used in adaptive systems. In the two
phases of this type of systems which use a STC-PID, the ...
Mathematical Analysis of Uncertainty
("Dunarea de Jos" University of Galati, 2008)
Classical Logic showed early its insufficiencies for solving AI problems. The
introduction of Fuzzy Logic aims at this problem. There have been research in the
conventional Rough direction alone or in the Fuzzy direction ...
Modelling Inteligent Systems With Level Petri Nets
("Dunarea de Jos" University of Galati, 2008)
Level Petri Nets are formalism for modeling hierarchical multi-agent system.
They are a Petri nets extension, allowing tokens to be nets themselves. This paper is
inspired by two classes of level Petri nets: object Petri ...
