The Nyquist plot is a graph of the magnitude and phase of a transfer function evaluated along the jw axis, with the graph displayed as. Real Axis Imag Axis ?1 ?0.5 0 ?1 ?0.8 ?0.6 ?0.4 ?0.2 0 0.2 0.4 0.6 0.8 1 Real Axis Imag Axis Figure 4.10: MATLAB Nyquist plot for Example 4.23 Relative stability assessments Using the Nyquist Plot. Note 2: In above example, evaluating the phase angle (?), at ?0+? yeilds a phase angle of ?-180 ?. An example of a Nyquist plot will illustrate what a Nyquist plot is. This will be later used in drawing the nyquist plot.
