Exercise 2 (4 points): A 2$^{nd}$-order system can be represented in either of the following two forms: One Way The 2$^{nd}$ Way $G(s) = \frac{b}{s^2 + as + b}$ $G(s) = \frac{\omega_n^2}{s^2 + 2\zeta\omega_n s + \omega_n^2}$ $\begin{cases} b = \omega_n^2 \\ a = 2\zeta\omega_n \end{cases} \iff \begin{cases} \omega_n = \sqrt{b} \\ \zeta = \frac{a}{2\sqrt{b}} \end{cases}$ $\omega_n$: natural frequency $\zeta$: damping ratio Conversion between a, b and $\omega_n$, $\zeta$ # G(s) Poles Undamped, underdamped, critically damped, or overdamped? Damping Ratio Step Response (1) $\frac{9}{s^2 + 9}$ (2) $\frac{9}{s^2 + 3s + 9}$ (3) $\frac{9}{s^2 + 9s + 9}$ (4) $\frac{9}{s^2 + 6s + 9}$ $\zeta = \frac{a}{2\sqrt{b}}$
