Bode Plot, Gain Margin and Phase Margin (Plus Diagrams)

WebThe gain margin is found by using the phase plot to find the frequency WGM, where the phase angle is 180°. This is shown in figure G below . By observing the magnitude plot at this frequency, the Gain margin GM can be determined, which is the gain required to raise the magnitude curve to 0 dB, shown in yellow colour. WebGm is the amount of gain variance required to make the loop gain unity at the frequency Wcg where the phase angle is –180° (modulo 360°). In other words, the gain margin is 1/g if g is the gain at the –180° phase frequency. Similarly, the phase margin is the difference between the phase of the response and –180° when the loop gain is 1.0.
