This project report details the development of position control for a DC motor using a PI controller. The author designs an algorithm to help with DC position control and tests the system in Simulink MATLAB by varying the controller gain values. In hardware tests, the author assembles a closed loop system and uses a potentiometer to test the motor's ability to reach different positions.

1. ABSTRACT
This project report presents the development of position control of DC
motor.We solve this classic DC position control problem with feedback
using PI controller.In addition to the control techniques for better performance
of the systems we need to design an algorithm which is helpful for DC position
control. Position Control is a type of automatic control in which the input
commands are the desired position of a body. Because of their high
reliabilities,
flexibilities and low costs, DC motors are widely used in industrial
applications,
robot manipulators and home appliances where speed and position control of
motor are required. PID controllers are commonly used for motor control
applications because of their simple structures and intuitionally comprehensible
control algorithms.
In this project we’ve done the software analysis on the software Simulink
MATLAB and we’ve also made the hardware. The software analysis was done
by changing the gain of the controller and the response was obtained for the
various values of the gain.
In hardware, the components were assembled in a close loop system and the
position of the motor was tested for different postions using potentiometer.
