A servomechanism, or 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.
Servomechanisms may or may not use a servomotor. For
example a household furnace controlled by thermostat is a
servomechanism, yet there is no closed-loop control of a
servomotor.
