hello,everyone
the plot is the open loop gain and phase versus frequency and the close loop gain is 18.however, i have many confusions about it.
1:what is the phase margin when the feedback factor is 1/18?
2oes the overshoot cause close loop instability?
3:Is it common to see the phase never achieve 180 degree?
thank you
