Electric Mechanic Interview Question:

Explain me why Negative Feedback is preffered in the Control System?

Submitted by: Muhammad

The role of Feedback in control system is to take the sampled output back to the input and compare output signal with input signal for error ( deviation from the desired result).
Negative Feedback results in the better stability of the system and rejects any disturbance signals and is less sensitive to the parameter variations. Hence in control systems negative feedback is considered.
