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

The project is designed to control AC power to a load by using firing angle control of thyristor. Efficiency of such power control is very high compared to any other method.

The project uses zero crossing point of the waveform which is detected by a comparator whose output is then fed to the microcontroller. The microcontroller provides required delayed triggering control to a pair of SCRs through opto isolator interface.

Finally the power is applied to the load through the SCRs in series. This project uses a microcontroller from 8051 family ....etc

ppt on a combination of shunt hybrid power filter and thyristor controlled reactor for power quality

This paper proposes a combined system of a thyristor-controlled reactor (TCR) and a shunt hybrid power filter (SHPF) for harmonic and reactive power compensation. The SHPF is the combination of a small-rating active power filter (APF) and a fifth-harmonic-tuned LC passive filter. The tuned passive filter and the TCR form a shunt passive filter (SPF) to compensate reactive power. The small-rating APF is used to improve the filtering characterist ....etc

DTMF Based Interfacing and Control of Induction Motor using TRIAC



The AC induction motor is the most commonly used AC motor in industrial application because of its simplicity, rugged construction, and relatively low manufacturing costs. The reason that the AC induction motor has these characteristics is because the rotor is a self-contained unit, with no external connections. This types of motor devices its name from the fact that AC currents are induced into the rotor by a rotating magnetic field.
Our project d ....etc

INTRODUCTION

Boost converter is one of the most popular choices for high-quality rectification. The converter is supplied from a full-wave rectified line voltage and operated so that the input current follows the input voltage. The input current shaping can be achieved using a number of techniques. When the converter is operated at fixed frequency and fixed duty ratio in the discontinuous conduction mode (DCM), the low- frequency component of the input current is approximately proportional to the input ....etc

Abstract

Direct Torque Control (DTC) is quite different from vector control and has several advantages compared to vector control. This paper presents intelligent control scheme together with conventional control scheme by fuzzy logic approach, to overcome the problems with uncertainties in the structure encountered with classical model based design. To adjust the speed of the direct torque control of induction motor drive, a fuzzy state feedback controller is pro ....etc

speed control of dc motor using thyristor dual converter with pid controller

ABSTRACT

The paper describes the design, construction and testing of a closed-loop system for the speed control of a separately excited d.c. motor fed from a dual converter. The dual converter makes possible regenerative braking and reversal of direction of rotation. There is only one firing unit and the firing pulses are diverted to the appropriate converter by a master controller. There are three control loops: one for armature current control, one for adjusting th ....etc
