Control Systems/Nyquist Stability Criteria Wikibooks
The first bode plot has a phase of -45 degrees at a frequency of 1 rad/s. Setting the phase matching options so that at 1 rad/s the phase is near 750 degrees yields the second Bode plot. Note that, however, the phase can only be -45 + N*360, where N is an integer, and so the plot is set to the nearest allowable phase, namely 675 degrees (or 2*360 - 45 = 675).... Stability from Bode Plots L(jω) Closed Loop System is stable provided the Gain of L(jω) is less than 1 AND the phase of L(jω) is less than 180o for all ω

Since the magnitude plot starts at a slope of –20 dB/dec we know that this is a type 1 system, so we have a pole at 0. We can also see this from the phase diagram since it start at –90°....

How To Draw Bode Plot In Control System Pdf

A careful inspection of the Nyquist plot will reveal a surprising relationship to the Bode plots of the system. If we use the Bode phase plot as the angle θ, and the Bode magnitude plot as the distance r, then it becomes apparent that the Nyquist plot of a system is simply the polar representation of the Bode plots.
