IMPLEMENTATION OF PID CONTROL TO REDUCE WOBBLING IN A LINE FOLLOWING ROBOT

Abstract: A Proportional-Integral-Derivative (PID) Control System provides for controlling the value of a variable, in this case the position of the robot, so that it is at or near a desired value, called the set-point, in this case on the centre of the line. In contrast to other control systems this provides for the smoothest type of control with minor deviations and overshooting if implemented correctly. This paper discusses, the concept, design and implementation of a line following robot that uses the PID control algorithm to govern its motion. The control algorithm is implemented in real time by a pre-programmed microcontroller.
