servo is an automatic device which uses error-sensing
feedback to correct the performance of a mechanism. The term
correctly applies only to systems where the feedback or
error-correction signals help control mechanical position or
other parameters. For example an automotive power window
control is not a servomechanism, as there is no automatic
feedback which controls position—the operator does this by
observation. By contrast the car's cruise control uses
closed loop feedback, which classifies it as a servomechanism.
