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 that to feedback path parameter changes
D. Equally sensitive to forward feedback path parameter changes
Answer:C
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 that to feedback path parameter changes D. Equally sensitive to forward feedback path parameter changes
Explanation: 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 change in H.
