If the gain of a critically damped system is increased, it will become
- A. Under damped system
- B. Over damped system
- C. Oscillatory system
- D. Critically damped system
Answer: A. Under damped system
Explanation: For a standard second-order system, increasing forward-path loop gain increases the natural frequency ωn without increasing the damping factor, reducing the damping ratio ζ below 1 (underdamped).
