    • 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 ...

    • Energetic Optimal Control of Adjustable Drive Systems 

      Roşu, Emil; Găiceanu, Marian; Bivol, Ion; Călueanu, Dumitru ("Dunareade Jos" University of Galati, 2002)
      In the paper is developed a new control strategy for the adjustable speed drives. The strategy consists in the energetic optimal control of the dynamic regimes as starting, stopping and reversing. The main developed ...

    • Indirect Control of a Single-Phase Active Power Filter 

      Roşu, Emil; Culea, Mihai; Dumitriu, Teodor; Munteanu, Traian ("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 ...

    • Low Power Battery Charger with Solar Panel Input, the Electronic Circuit 

      Epure, Silviu; Roşu, Emil ("Dunarea de jos" University of Galati, 2011)

    • Optimal Control Development System for Electrical Drives 

      Găiceanu, Marian; Roşu, Emil; Păduraru, Romeo; Dache, Cristinel ("Dunarea de Jos" University of Galati, 2008)
      In this paper the optimal electrical drive development system is presented. It consists of both electrical drive types: DC and AC. In order to implement the optimal control for AC drive system an Altivar 71 inverter, a ...

    • A Simple Load Power Estimator for Quasi-Direct AC-AC Converter System 

      Găiceanu, Marian; Roşu, Emil ("Dunarea de Jos" University of Galati, 2003)
      In this paper a simple load power estimator for the three-phase quasi-direct acac converter system is reported. Since the ac-ac converter control by means of pulsewidth modulation (PWM) is based on the power balance ...
