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.

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.

Answer / er. ankush miglani

first of all it is servomechanism not sero mechanism
it s used to serve any system an error free mechanism
it uses a feedback signal for the correction of the output
signal'
