In closed loop control system, what is the sensitivity of the gain of the overall system, M to the variation in G?

A)

1/1+GH

B)

1/1+G

C)

G/1+G

D)

G/1GH

Correct Answer : Option (A) : 1/1+GH

Explanation : The sensitivity of the control system is defined as the change in the outputs to the change in the input and senstivity of the gain of the overall system, M to the variation in G is 1/1+GH.
