Well!!!! close loop system is kind of atumatic system that
have a feed back device which measure the actual value and
then feed this value back to controller then controller
compare the setpoint & the actual value (get from feed back
device)after this control generate + or - signals/
correction to final control element ( that is responsible
for controling the variable quantities).
so if your system have a controller with feedback device,
final control element then it will be a close loop system
