Active Power Compensator of the Current Harmonics Based on the Instantaneous Power Theory
("Dunarea de Jos" University of Galati, 2005)The quality of the electrical current becomes a major concern. The proliferation of the power electronic converters, which are used extensively to control electrical apparatus in industrial and commercial applications (dc ... -
Dc Link Current Estimation in Wind-Double Feed Induction Genera Power Conditioning System
("Dunarea de Jos" University of Galati, 2010)In this paper the implementation of the DC link current estimator in power conditioning system of the variable speed wind turbine is shown. The wind turbine is connected to double feed induction generator (DFIG). The ... -
Energetic Optimal Control of Adjustable Drive Systems
("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 ... -
Model Predictive Speed Control for Three Phase Induction Motor
("Dunarea de Jos" University of Galati, 2013)In this paper an alternative method to the classical control of the induction motor drive system is proposed. More exactly, a model predictive control (MPC) for the rotor speed of the induction motor is presented. The ... -
Model Reference Adaptive Control of a Vector Controlled Three Phase Induction Machine
("Dunarea de Jos" University of Galati, 2011)Model reference adaptive control (MRAC) of three-phase induction machine in rotor field coordinated is proposed in this paper. The proposed adaptive structure is in direct form, such that the controller parameters are ... -
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. ... -
Optimal Control Development System for Electrical Drives
("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 ... -
Optimal Control for Electric Vehicle Stabilization
("Dunarea de Jos" University of Galati, 2010)This main objective of the paper is to stabilize an electric vehicle in optimal manner to a step lane change maneuver. To define the mathematical model of the vehicle, the rigid body moving on a plane is taken into ... -
Performance Comparison of Sliding Mode Controller and Conventional Pid Controller for DC Motor
("Dunarea de Jos" University of Galati, 2013)This paper is concerned with the performance comparison of Sliding Mode Controller and conventional PID Controller for the control of DC Motor. The DC motor can be modeled as a linear time invariant single input single ... -
Power Conditioning System Topology For Grid Integration of Wind and Fuel Cell Energy
("Dunarea de Jos" University of Galati, 2006)This paper shows the topology of the hybrid grid-connected power system and the performances of the front-end three-phase power inverter. The renewable sources of the hybrid power system consist of a solid oxide fuel cell ... -
A Simple Load Power Estimator for Quasi-Direct AC-AC Converter System
("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 ...
