An increase in gain, in most systems, leads to_____________?
Correct answer: A. smaller damping ratio
- A. smaller damping ratio
- B. larger damping ratio
- C. constant damping ratio
- D. none of the above
Explanation
Increasing loop gain commonly moves the dominant closed-loop poles toward lower damping, producing more overshoot and oscillation. Thus the damping ratio generally becomes smaller, although special system structures can behave differently.
