WebI'm using Matlab to create a lead-lag controller with certain specifications (university course), and to find the compensator value, I wanted to use the margin() function to find and plot the gain and phase margins. However, Matlab calculates a phase margin of infinity, when I can see that the phase margin is approximately 18 in the plot itself. WebExplanation: Gain margin of a polar plot passing through the critical point is zero. What does a Gain margin close to unity or phase margin close to zero indicate? Hence a Gain …

WebThe gain margin is the factor by which the gain must be multiplied at the phase crossover to have the value 1. The phase crossover occurs at 0.010 Hz and so the gain margin is 1.00/0.45=2.22. The phase margin is the number of degrees by which the phase angle is smaller than 180 at the gain crossover.
