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

AUTOMATIC TEMPERATURE CONTROL IN VACUUM BRAZING FURNACE USING P.L.C

ABSTRACT
The main objective of this project is to maintain & control temperature uniformly of the two zones in vacuum brazing furnace and braze similar or dissimilar components using certain chemicals, for the given specifications of a job
Brazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel ....etc

Introduction

While going through the paper about various innovative technologies in the modern electronics world we came across the concept of fuzzy in the paper titled “ Implementation of fuzzy temperature control using microprocessor”. We found this concept to be quite interesting and we decided to implement this concept using microcontroller.
When Lotfi Zadeh introduced the world to fuzzy logic in 1965, he forgot to include, or rather was unprepared to include a us ....etc

Abstract


An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions, often with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, can do many different tasks depending on programming. Embedded systems control many of the common devices in use today.
Since the embedded system is dedicated to specific tasks, design ....etc
