Constructing nyquist plot from polar plot

  1. Mar 14, 2013 #1
    Is it possible to construct Nyquist plot from polar plot (ω varies from ∞ to 0) ?

    Yes, for a system with no poles or zeros on the Nyquist path, the Nyquist diagram is simply the polar plot of the open-loop function along with its complex conjugate.
