ABSTRACT
In today's fast moving World, the accidents are increasing at a very fast rate. One of the major causes of these accidents is over a speeding of vehicles. A major step has been taken rather to increase the road safety, so as to minimize the accidents

One of a major development was the introduction of speed cameras. This camera, usually containing radar, is electronic devices those working are still a mystery to most electronic hobbyists. The principle of these speed cameras is Doppler Eff ....etc

Definition

Although there is good road safety performance the number of people killed and injured on our roads remain unacceptably high. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The road safety strategy includes all forms of invention based on the engineering and education and enforcement and recognizes that there are many different factors that lead to traffic collisions and casualties. The main reason is speed of vehicle. We use traffic lights and other traffic manager to reduc ....etc

A variable-speed controller, for an existing 225 kW fixed-speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind speeds. This algorithm is based on direct activ ....etc

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

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.
