Question

Feedback control systems are (A) insensitive to both forward- and feedback-path parameter changes (B) less sensitive to feedback-path parameter changes than to forward-path parameter changes (C) less sensitive to forward-path parameter changes than to feedback-path parameter changes (D) equally sensitive to forward- and feedback-path parameter changes

Answer 1

Answer:

Option C

Explanation:

Feedback plays an important role in order to improve the performance of the control systems. Feedback control system can be positive and negative but positive feedback systems less widely used as the positive feedback systems are more sensitive to parameter variations but negative feedback are less sensitive to change in G than a change in H.
