PID is a control 'filter' , which helps you get to a goal setpoint as fast as possible without overshoot or oscillation. The technique is siple realy:
The algorithim gives more power to the motor when it's further from the target, and less power when it's close to the target.
By choosing the Kp, Kd and Ki terms properly you can 'tune' the filter to respond smoothly and rapidly to any position demand without overshooting.
