Loop Analysis Caltech Computing

We can verify our answers by zooming in on the Nyquist plots as well as by looking at the closed-loop step responses for gains of 0.79, 0.80, and 0.81. Gain Margin We already defined the gain margin as the change in open-loop gain expressed in decibels (dB), required at -180 degrees of phase shift to make the open-loop magnitude equal 0 dB.

Lecture 6Gain Phase margins designing with Bode plots

What follows are several examples of Nyquist plots. In general each example has five sections: 1) A definition of the loop gain, 2) A Nyquist plot made by the NyquistGui program, 3) a Nyquist plot made by Matlab, 4) A discussion of the plots and system stability, and 5) a video of the output of the NyquistGui program.
