Detecting the Liquid core in Continuous Casting Slabs by Load Torque Estimation in Unbending Zone
("Dunarea de Jos" University of Galati, 2002)
The development in continuous casting process has been strongly dominated
by the demands of quality improvement and reduced costs for steel products in recent
years. To achieve these goals consideration has been given ...
Real Time wind Turbine Simulator Based on Frequency Controlled Servomotor
("Dunarea de Jos" University of Galati, 2002)
This paper is a contribution to the development of a real time wind turbine
simulator. The simulator is designed to generate wind power on its shaft, and provide the
static and dynamic characteristics of a given turbine. ...
Adaptive Filter Used as a Dinamic Compensator in Automatic Gauge Control of Strip of Rolling Proceses
("Dunarea de Jos" University of Galati, 2010)
The paper deals with a control structure of the strip thickness in a rolling mill
of quarto type (AGC – Automatic Gauge Control). It performs two functions: the
compensation of errors induced by unideal dynamics of the ...
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 ...
Estimation of Steel Solidified Layer Thickness, for Continuous Casting Control Purposes
(2008)
An important goal in continuous casting automation process rest in
establishing a proper casting speed being able to assure a compromise between machine
productivity and solidified skin cracking protection on the mould ...
MPPT Algorithm for Small Wind Systems Based on Speed Control Strategy
("Dunarea de Jos' University of Galati, 2008)
This paper presents experimental results of an autonomous low-power wind
energy conversion system (WECS), based on a permanent-magnet synchronous
generator (PMSG) connected directly to the wind turbine. The purpose of ...
Force Prediction in Cold Rolling Mills by Polynomial Methods
("Dunarea de Jos" University of Galati, 2007)
A method for steel and aluminium strip thickness control is provided including a new technique for predictive rolling force estimation method by statistic model based on polynomial methods.
Optimal Control Structure for Variable Speed wind Power System
("Dunarea de Jos" University of Galati, 2002)
This paper presents an optimal control structure for variable speed, fixed pitch
wind turbine. The control objective results from the optimization criterion that includes
two contradictory demands: maximization of the ...
Modelling Non-Stationary Wind Speed for Renewablwe Energy Systems Control
("Dunarea de Jos" University of Galati, 2001)
This paper deals with the modelling of the wind speed, treated as a nonstationary
process. In the proposed modelling methods, the wind speed has two
components: a long and medium term-component, described by an available ...
