2 MRAS Based Speed Sensorless Control of Induction Motor Drives

Authors: Nadia Bensiali, Amar Omeiri, Nadia Benalia

Abstract:

The recent trend in field oriented control (FOC) is towards the use of sensorless techniques that avoid the use of speed sensor and flux sensor. Sensors are replaced by estimators or observers to minimise the cost and increase the reliability. In this paper an anlyse of perfomance of a MRAS used in sensorless control of induction motors and sensitvity to machine parameters change are studied.

1 Sensorless Control of Induction Motor: Design and Stability Analysis

Authors: Nadia Bensiali, Erik Etien, Amar Omeiri, Gerard Champenois

Abstract:

Adaptive observers used in sensorless control of induction motors suffer from instability especally in regenerating mode. In this paper, an optimal feed back gain design is proposed, it can reduce the instability region in the torque speed plane .

Keywords: adaptive observer, induction motor drive, regenerating mode, stabilizing design

1 A Three Phase Shunt Active Power Filter for Currents Harmonics Elimination and Reactive Power Compensation

Authors: Amar Omeiri

Abstract:

This paper presents a three-phase shunt active power filter for current harmonics suppression and reactive power compensation using the supply current as reference. The proposed APF has a simple control circuit; it consists of detecting the supply current instead of the load current. The advantages of this APF are simplicity of control circuits and low implementation cost. The simulation results show that the proposed APF can compensate the reactive power and suppress current harmonics with two types of non-linear loads.

Keywords: Power Quality, total harmonic distortion, PWM inverter, active power filter, current harmonics and reactive power compensation
