!!! Proportional–Integral–Derivative (PID) Controller
This page describes information about a ''Proportional–Integral–Derivative Controller'' (PID controller or three-term controller). Rather than rely on the voltage sent to the motors to determine their speed (with
each motor and gearbox requiring slightly different voltages) this uses a __[motor encoder|MotorEncoder]__ that measures the speed of the motors themselves, then uses that to determine the difference between the intended
and actual motor speeds. This is used to determine the distance each motor has traveled.
