SPEED CONTROL OF AN INDUCTION MOTOR USING INDIRECT VECTOR CONTROL
ABSTRACT
Over the past two decades technological advances in power electronics and an increasing demand for high performance industrial machinery have contributed to rapid developments in digital motor control. This field of study has numerous applications in the areas of manufacturing, mining and transportation but sometime it is difficult to determine which technique is best suited to a particular application.
Induction motor is used as a variable speed drive in many indus ....etc

mini projet report
Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc

INTRODUCTION
This assignment is basically designed to demonstrate the use of controllers in DC motor which consists of two stage ,electronic stage that is controlled by 8 bit microcontroller and second is the mechanical stage consisting of gear box which controls the motion of DC motor to provide a impulse to electronic stage which generates a resultant signal to control the parameters of controller.
FEEDBACK-CONTROL THEORY

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

A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches
Abstract
A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc
