Analysis and Experimental Verification of Series Resonant PFC DC to DC Converter
("Dunarea de Jos" University of Galati, 2010)
The aim of this work is to simulate and implement Series Resonant PFC DC –
DC converter using Matlab Simulink. The quality of power consumption in terms of
power factor and electromagnetic interference (EMI) levels are ...
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 ...
Simulation of four Switch PWM AC Chopper Fed Single Phase Induction Motor
("Dunarea de Jos" University of Galati, 2010)
To improve the performance of motor drives, there is a need to improve the
quality and reliability of the drive system. With the high power handling capability of
IGBT, pulse width modulated AC chopper can be used in ...
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 ...
Decomposition Methods to Optimise the Structure and Parameters of Transfer line with Parallel and Sequential Machining
("Dunarea de Jos" University of Galati, 2003)
The paper is devoted to a preliminary design problem of paced automatic
transfer lines. At this design stage, the following decisions are to be made: the
partitioning of the given set of operations into subsets performed ...
A Novel Parametric Model for the Human Respiratory System
("Dunarea de Jos" University of Galati, 2003)
The purpose of this work is to present some recent results in an ongoing
research project between Ghent University and Chess Medical Technology Company
Belgium. The overall aim of the project is to provide a fast method ...
Transducer-Shape Optimization for Angle Estimation of a Broadbrand Monaural Sonar System
("Dunarea de Jos" University of Galati, 2004)
In this paper we describe a procedure for the search of the optimal trans-ducer geometry for a monaural, broadband sonar system. We restrict ourselves to a simple transducer morphology that can be technologically realized: ...
The Disturbance Model in Based Predictive Control
("Dunarea de Jos" Univesity of Galati, 2003)
Model Based Predictive Control (MBPC) is a control methodology which
uses a process model on-line in the control computer; this model is used for calculating
output predictions and optimizing control actions. The importance ...
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 ...
