You are testing a new device to determine its characteristics. You find the magnitude of its frequency response shows a peak at 500 Hz, and the measured overshoot of the step response is 40% of the steady state level. Find the system’s characteristics and confirm your answers by generate plots of its frequency and step response using either Simulink or Pspice.
I'm trying to figure out how to find the natural frequency with the given info.
$\frac{500\,\text{Hz}}{140\,\%}\approx 357.145$; I'm assuming my $r_o = 357.145$, where we settle at.
Given percentage overshoot (40%) I can solve for our damping ratio $\zeta = 0.279$. I have formulas to solve for Natural Frequency ($\omega_n$) but not enough known variables to solve for it. Does anyone know how to solve for $\omega_n$ here?
In our case, $\beta = 1.288$, if that helps.
