Now find the gain and phase crossover frequencies There are two ways to do this Firstfrom the magnitude and phase angle plots we can make a good guess at where w 1 awp are respectively and solve the necessary equations Or we could find where the twocurves plotted on each the magnitude and phase angle plots intersect by setting themequal to each other and solving for w Both ways are shown here Solve for w 1 by using thegraph and for w p by using the equations
Input a guess value for w 1 based on the magnitude plot intersection and change it untilthe answer to the |GH(w)| function is unity
For w p set the phase equation equal to -180 deg (or -p) and use the root function
Guess
Therefore the gain margin is
And the phase margin is

Now find the gain and phase crossover frequencies There are two ways to do this Firstfrom the magnitude and phase angle plots we can make a good guess at where w 1 awp are respectively and solve the necessary equations Or we could find where the twocurves plotted on each the magnitude and phase angle plots intersect by setting themequal to each other and solving for w Both ways are shown here Solve for w 1 by using thegraph and for w p by using the equations
Input a guess value for w 1 based on the magnitude plot intersection and change it untilthe answer to the |GH(w)| function is unity
For w p set the phase equation equal to -180 deg (or -p) and use the root function
Guess
Therefore the gain margin is
And the phase margin is
