SPEED CONTROL OF DC SHUNT MOTOR USING MICRO CONTROL BASE


INTRODUCTION:-
DC motor speed controllers are very useful for controlling the motion of robotic and industrial automation systems. The controller presented here uses the PWM technique. The PMW wave for speed control is generated using Atmel AT89C51 microcontroller. To control the speed of the DC motor, you need a variable power supply. When the DC motor is switched on, i ....etc

IMPLEMENTATION OF DSP BASED SENSORLESS CONTROL WITH
DIRECT BACK-EMF DETECTION METHOD FOR BLDC MOTOR

ABSTRACT
This thesis presents a back EMF sensing scheme, direct back EMF detection, for
sensorless Brushless DC (BLDC) motor drives with a DSP based controller. Using this
scheme, the motor neutral voltage is not needed to measure the back EMF. Instead the
method utilizes the high-speed A/D converter channels, which are available on a DSP
controller. The true back EMF of the floating motor winding is detecte ....etc

The Impact of Control Delay upon the Performance of a DC-Motor Control: Comparison of a Centralized vs. a Network-Based Approach
Abstract
An important aspect when dealing with computer control systems is the impact of control delay upon the performance of the controlled item. Such control delay may be a consequence of the computer controlled implementation or, for the case of a network based control system, can be the consequence of the use of a communication network to interconnect sensors and actuators with the controller. Ba ....etc
