ABSTRACT
Now a day's every system is automated in order to face new challenges in the present day situation. Automated systems have less manual operations, so that the flexibility, reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance.
This project mainly deals with the speed control of a AC Motor using a P.C. The type of speed control that has been chosen here is pulse width modulation PWM. This project deals with development of AC MOTOR control using P.C,. 12V DC Motor drives widely use Micro controllers and The project detail design and complete hardware based high performance AC drive control system will be implemented. Most recently new requirements have arisen. These include faster torque control update with flexible design capability of motion peripherals for high performance military drive applications. Pulse width modulation type of speed control is chosen here because of high accuracy, high reliability, quick response and high efficiency.
Our project deals with the types of problems that we face due to disturbances in supply voltage or load on the motor and enables us to overcome these difficulties by helping us with the appropriate software and hardware.
We propose to design an embedded controller that helps us maintain the speed of the DC machine within the specific limits and a remote operate the embedded controller. Here, the pulses from the remote are sensed by sensor and are transmitted to the embedded controller. This controller contains a programmable PWM port. The output of this PWM port is used to control power delivered by a power regulating device
INTRODUCTION
The potentiality of any country depends upon its sound economy. After the Second world War, the economy of Western countries in general and Japan in particular were chattered into peace. It was a Herculean task for them to rebuild economy and the only one left to them was to accelerate their Industrial Production by resorting to a newer technology called “Automation.”
Today the Western Countries and Japan are able to rebuild their economy and compete in the world market of goods so efficiently keeping the quality as Top and the cost highly competitive because of the application of AUTOMATION Techniques Automobile industries without limitation on other industries have been automated at in these countries.
Automation is progressively increasing the productivity and hence, the profitability of most large organization by rapidly becoming more efficient and competitive by their methods of production and management. Small Industries with few exceptions, perhaps, are not progressing to anything like the same extent and in consequence their profitability is for too low for stability and growth. The efficiency of small industries is however, of vital importance to the economy of the country, they represent over 90% of all industries, employ about half those engaged in large industries and produce nearly half of all manufactured goods.

REGULATED POWER SUPPLY
DESCRIPTION
A variable regulated power supply, also called a variable bench power supply, is one where you can continuously adjust the output voltage to your requirements. Varying the output of the power supply is the recommended way to test a project after having double checked parts placement against circuit drawings and the parts placement guide. This type of regulation is ideal for having a simple variable bench power supply. Actually this is quite important because one of the first projects a hobbyist should undertake is the construction of a variable regulated power supply. While a dedicated supply is quite handy e.g. 5V or 12V, it's much handier to have a variable supply on hand, especially for testing.
Most digital logic circuits and processors need a 5-volt power supply. To use these parts we need to build a regulated 5-volt source. Usually you start with an unregulated power supply ranging from 9 volts to 24 volts DC. To make a 5 volt power supply, we use a LM7805 voltage regulator IC (Integrated Circuit). The IC is shown below.
