Second order systems Flashcards
1
Q
How can natural frequency and the damping factor be determined via comparison?
A
Using the equation AWn^2 / s^2 +szWn + Wn^2
and the TF of a second order system
(typically bo/ s^2 +a1s + a2)

Q
How can omega and zeta be determined from the time response?
A
- consider 2 time points where the sinusoid is at its maximum
- ∆t = 2π / wd
- Assess the ratio of the peak magnitudes
