What is CL (closed-loop)?

Closed-loop systems utilize feedback where a part of the output signal is fed back to the input to decrease errors and enhance stability. An open-loop control system can be changed into a closed-loop control system by applying feedback. This feedback automatically makes changes in the output due to outer disturbance. Close loop is exceptionally precise as any error emerging is corrected because of the presence of a feedback signal. It gives a large bandwidth range and Facilitates automation. The sensitivity of the framework may be made little to make the framework more stable. This framework is less influenced by noise.
