Closed loop control system
A control system in which the objective is that the controlled quantity attain a desired performance and be then measured and compared with a standard representing that performance.
Note:: Any deviation from the standard is fed back into the control system in such a sense
that it will reduce the deviation of the controlled quantity from the standard.
