Bode Plot and resonant peaks
Hello,
I’m trying to fit these points to get a bode plot and possible transfer function
w = [0.1 0.2 0.3 0.5 0.8 1 2 3 5 8 10 20 30 50 80 100 200 300 500 800 1000 2000 3000 5000 8000];
G = [0 0 0 0 0 0 0 10 22 28 33 38 35 33 30 28 20 14 8 0 0 0 0 0 0];
I know there is a zero at 2 and the increasing is steeper so started with
"s^2+4*s+4" on the numerator
I know there is a resonant peak at x = 20 but I’m unable to do it.
Also. how to make the bode plot stop at 0 ?
you can find my try here with this transfer function :H=((s^2+4*s+4))/((s+30)^3);
