Hankel-Norm Approximation Method Applied for High Order Model Reduction to Robust Contriller Synthesis
Copot, Cosmin; Ionescu, Clara M.; De Keyser, Robain; Dugan, Viorel ("Dunarea de Jos" University of Galati, 2012)In this paper, is presented an application of the Hankel–norm approximation method for model order reduction, to obtain a lower order model with the same performance. In order to show the effectiveness of the Hankel-methodologie ... -
Limitations of a Static VAr Compensator (SVC) with Switched Capacitor Operating as an Active Filter
Judele, Stelian; Solea, Răzvan; Dugan, Viorel ("Dunarea de Jos" University of Galati, 2001)The goal of this paper is to analyze the limitations of a static VAr compensator (SVC) with switched capacitor, when this operate as an active filter. The limitations considered and studied by simulation are in the zone ... -
On the Snubber Influence to the Switching and Conduction Losses in a Converter Using Switched Capacitor
Judele, Stelian; Solea, Răzvan; Dugan, Viorel ("Dunarea de Jos" University of Galati, 2002)The paper deals to design and to compute the snubber parameters influence on the switching and conduction losses of the transistors (IGBT) used as bidirectional switches in a converter with switched capacitor. The converter ... -
Pid Self-Tuning Controllers Used in Different Structures of the Control Loops
Dugan, Viorel; Dan, Adrian; Ionescu, Clara; Cotrumba, Mirela ("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 ... -
Three Fuzzy Reasoning Models as a Decisionsuport AID, to Find an Electrical Energy Tariff
Dugan, Viorel; Solea, Răzvan; Ionescu, Clara; Ghiniţă, Daniela ("Dunarea de Jos" University of Galati, 2005)This contribution is a laboratory-work developed as an example of approximate (fuzzy) reasoning for students, possible to be used as a decision – support to estimate an electrical energy (EE) price for consumers. The three ...
