Contribuții privind algoritmii de prelucrare a semnalelor și conducere automată a convertoarelor statice de putere cu rol de filtre active
(Universitatea "Dunărea de Jos" din Galați, 2008) -
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 ... -
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 ... -
On Process Modelling Using Physical Oriented and Phenomena Based Principles
("Dunarea de Jos" University of Galati, 2000)This work presents a modelling framework based on phenomena description of the process. The approach is taken to easy understand and construct process model in heterogeneous possible distributed modelling and simulation ... -
On the harmonics reduction using wavelet based signal processing
("Dunarea de Jos" University of Galati, 2000)This paper presents a method for calculating the reference currents needed for the command of an active filter. By using the Discrete Wavelet Transform (DWT) the high-frequency components of the currents are eliminated. ... -
On the Performances of Different types of Controllers for Active Power Filters
("Dunarea de Jos" University of Galati, 2004)This paper analyses the performances of three different types of controllers for shunt active power filters. The controllers are used in the d-q frame, the same frame in which the reference signal for the 5th and 7th ... -
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 ... -
Stationary Frame Active Power Filter Control Based on Multiresolution Analysis
("Dunarea de Jos" University of Galati, 2006)The paper presents an active power filter control method. The reference signal is generated in the stationary reference frame α-β using multiresolution analysis and the controllers used are P-resonant controllers, suitable ...
