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

Multilevel voltage source converters are emerging as a new breed of power converter options for high-power applications. Here, staircase voltage wave is generated from several levels of dc capacitor voltages. the voltage unbalance between different levels is the major disadvantage of multilevel converters. voltage clamping or capacitor charge control are the main techniques used to solve this. The following types of multilevel voltage source converters are described here:
a)diode-clamp: The diode-clamp method can be applied to highe ....etc

Presented By:
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

Abstract.
In this paper a novel modular digital controlalgorithm for multi level inverters is introduced and discussed.This algorithm is essentially based on the duty cycle expressionand allows a great simplification, because of its modularity andits simple implementation. The algorithm is particularly suitablefor the Multi Point Clamped (MPC) inverters with no constrainton the number of the voltage levels and results faster than themost recent solutions proposed in literature.The modulation techniques considered in the paper are the ....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
