Which of the following are the not characteristics of the closed loop systems?

A)

It does not involve I/O measurements

B)

It does not compensate for disturbance

C)

It reduces the sensitivity of plant-parameter variations

D)

It does not have the ability to control the system transient response

Correct Answer : Option (D) : It does not have the ability to control the system transient response

Explanation : Feedback refers to the comparison of the final output to the desired output at respective input so as to get accurate and error free result and in the system improves the transient response of the system.
