Mustapha MESSAOUDI, Habib KRAIEM, Mouna BEN HAMED, Lassaad SBITA and Mohamed Naceur ABDELKRIM

Abstract
In this paper, the classical Direct Torque Control (DTC) of Induction Motor (IM) using an open loop pure integration suffers from the well-known problems of integration especially in the low speed operation range is detailed. To tackle this problem, the IM variables and parameters estimation is pe ....etc

SPEED SENSORLESS SEPARATELY EXCITED DC MOTOR DRIVE WITH AN ADAPTIVE OBSERVER


ABSTRACT
This project deals with a speed sensorless separately excited dc motor drive which uses the adaptive observer to estimate the rotor speed. The stability analysis of speed estimation is carried out. The modified feed forward control is integrated with the adaptive observer to simplify the implementation. The design guideline for feedback gain and the speed controller are also given to assure system stability for the entire oper ....etc

FLUX ESTIMATORS FOR SPEED-SENSORLESS
INDUCTION MOTOR DRIVES



Abstract

This thesis deals with flux estimators for speed-sensorless induction motor drives. To enhance
the stability and the performance of state-of-the-art sensorless drives, new flux estimator
designs based on the standard motor model are proposed. Theoretical and experimental
research methods are both used. The dynamics and stability of flux estimators
are analyzed using linearized models, and the effects of parameter errors are investig ....etc

Sensorless Indirect Stator Field Orientation Speed Control for Single-Phase Induction Motor Drive
Abstract
The industrial requirements for the control of an inductionmachine without a mechanical sensor continue to be ofinterest, as evidenced by the most recent publications. The focusis on improvements of control without a mechanical sensor. A newmethod for the implementation of a sensorless indirect stator-fluxorientedcontrol (ISFOC) of a single-phase induction motor (SPIM)drive is proposed in this paper. The proposed method of rotor ....etc

Robust Adaptive Variable Structure Control Law

ABSTRACT
A novel sensorless adaptive robust control law is proposed to improve the trajectory tracking performance of induction motors. The proposed design employs the so called vector (or field oriented) control theory for the induction motor drives and the designed ....etc

Abstract
In this paper, a sensorless induction motorparameter identification is presented. Sensorless control employsa variety of estimators and observers of motor speed, torque andfluxes, and accurate information about motor parameters iscrucial to obtain a high performance control. The parameters ofthe induction motor equivalent circuit are obtained by means ofDC an AC tests using the voltage-source inverter. When theseparameters are estimated a closed loop flux estimator and an openloop speed estimator are implemented to determine ....etc
