The role of feedback system in control system is to check deviation from the desired result, that is, it takes the sample output back to the input and compares the output signal with the input signal for any kinds of error. Negative feedback results in a better stability for the system. It rejects any kind of disturbance signal and is less sensitive to any kind of parameter variations.
