    • Adaptive Filter Used as a Dinamic Compensator in Automatic Gauge Control of Strip of Rolling Proceses 

      Roman, N.; Ceangă, Emil; Caraman, Sergiu; Bivol, Ion; Barbu, Marian; Alexiu, Mugur George ("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 ...

    • Detecting the Liquid core in Continuous Casting Slabs by Load Torque Estimation in Unbending Zone 

      Bivol, Ion; Roşu, Emil; Ceangă, Emil ("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 ...

    • Estimation of Steel Solidified Layer Thickness, for Continuous Casting Control Purposes 

      Munteanu, Mihai; Ceangă, Emil (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 ...

    • Force Prediction in Cold Rolling Mills by Polynomial Methods 

      Roman, Nicu; Aiordăchioaie, Dorel; Ceangă, Emil; Bivol, Ion ("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.

    • Modelling Non-Stationary Wind Speed for Renewablwe Energy Systems Control 

      Nichita, Cristian; Luca, Daniel; Dakyo, B.; Ceangă, Emil; Cutululis, Nicolaos Antonio ("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 ...

    • MPPT Algorithm for Small Wind Systems Based on Speed Control Strategy 

      Vlad, Ciprian; Ceangă, Emil ("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 ...

    • Optimal Control Structure for Variable Speed wind Power System 

      Cutululis, Nicolaos Antonio; Munteanu, Iulian; Ceangă, Emil; Culea, Mihai ("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 ...

    • Real Time wind Turbine Simulator Based on Frequency Controlled Servomotor 

      Cutululis, Nicolaos Antonio; Ciobotaru, Mihai; Ceangă, Emil; Roşu, Mina Emil ("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. ...

    • Some Rezults Concerning No-Storage Wide-Diesel Systems Control 

      Vlad, Ciprian; Cutululis, Nicolaos Antonio; Lefebvre, Julie; Ceangă, Emil ("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 ...
