For an under damped second order control system, if damping increases, the settling time :
Answer: A
The settling time decreases.
For an underdamped second-order system the response settles within an envelope \(e^{-\zeta\omega_{n}t}\), and the settling time on the 2% criterion is about
\[ t_{s} \approx \frac{4}{\zeta\omega_{n}} \]
For a fixed natural frequency \(\omega_{n}\), a larger damping ratio \(\zeta\) makes the envelope decay faster, so \(t_{s}\) falls. It varies inversely with \(\zeta\), not with its square, and it is certainly affected by damping.
