Mechanical Engineering QUESTION #2388

Question 357

The standard second-order closed-loop transfer function is written as:

$Y(s) = \frac{2\zeta\omega_n}{s^2+2\zeta\omega_n s+\omega_n^2}$
$Y(s) = \frac{\omega_n^2}{s^2+2\zeta\omega_n s+\omega_n^2}$✔️
$Y(s) = \frac{\omega_n^2}{s^2+\omega_n^2}$
$Y(s) = \frac{1}{s^2+2\zeta s+1}$

Correct Answer Logic:

The standard second-order system: $Y(s)=\frac{\omega_n^2}{s^2+2\zeta\omega_n s+\omega_n^2}$ where $\omega_n$ is the undamped natural frequency and $\zeta$ is the damping ratio. Poles: $s=-\zeta\omega_n\pm\omega_n\sqrt{\zeta^2-1}$.
