If the gain of the critical damped system is increased it will behave as______________?
Correct answer: D. underdamped
- A. oscillatory
- B. critically damped
- C. overdamped
- D. underdamped
- E. none of the above
Explanation
For the usual second-order feedback system, increasing gain beyond the critical value reduces the damping ratio below one. The response therefore becomes underdamped and oscillatory.
