Hello, (sorry I'm french..)
I have a transfert fonction, for example Gs=5/(s²+s+1).
I can found "gain margin" and "phase margin" with functions:
g_margin and p_margin .
But how can I find the Crossover Frequency corresponding ?
With the Bode diagramm, the crossover frequency is near (close) to : w0=2,33 rad/s
Does it exist a direct function?
Thank you for your aswer.
[gm,fr]=g_margin(h)Where h is the Transfer function
