ABSTRACT

Stepper motor rotate by applying sequence of pulses to the stepper Motor coils. Speed of the motor is based on the sequence of pulses to the motor. Direction can be change by changing the pulse sequence inversely. Here in this project pulse is getting from PIC Microcontroller. It s a Programmable Peripheral Interface controller. Here keypad, Stepper motor Driver both are interfaced with the PIC Microcontroller. Keypad is used to vary the speed and to change the direction Of the stepper motor.

Controller output is given in ....etc

On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....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
Figure 1 shows the block diagram of a closed-loop system. In this configuration a ....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, it take the certain time to reach the full speed. As ....etc
