1. Introduction
This application note describes how to implement a brushless DC motor control in
sensor mode using the ATmega32M1 AVR microcontroller.
The high performance AVR core fitted with Power Stage Controller module of
ATmega32M1 allows to design high speed brushless DC motor applications.
In this document, we will give a short description of brushless DC motor theory of
operations, we will detail how to control a brushless DC motor in sensor mode and we
will also give a short description of the ATAVRMC310 and ATAVRMC300 b ....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

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
This paper presents a control scheme combined with neural network, fuzzy controller and PI- controller for the brushless DC motor. The neural network control learned continuously and gradually becomes the main effective control. Performances of the proposed neural network are compared with the corresponding fuzzy PI controller and conventional PI controller. Matlab/simulink software was used to simulate the proposed scheme. Neural network improves speed response and ....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

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

Adaptive Integral Position Control Using RBF Neural Networks for
Brushless DC Linear Motor Drive
Abstract
The paper presents an adaptive integral positioncontroller usingRBF (Radial Basis Function) neural networks (NNs)for a brushless DC linear motor. By assuming that the upper boundsof the nonlinear friction and force ripple, an RBF NN is used forapproximating the friction, the force ripple and the load; an adaptivebackstepping control with integral action is then proposed to achieveposition tracking of the linear motor. The paramete ....etc
