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 ...
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 ...
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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
