Answer / carl_ellis
PID provides a modulated output response to an error signal,
where error is the difference between what you want, the
setpoint, and what you have, the process variable.
PID uses an output response proportional to the input span
(P = proportional), modified by the accumulated error over
time (I = integral) and modified by the rate-of-change of
the error (D=derivative).
