Concept:
  • Nyquist plot crosses the negative real axis at phase cross over frequency (ωpc)
  • The phase crossover frequency is the frequency at which the phase angle first reaches −180°
  • i.e., ∠(G(ωpc)) = -1800
Calculation:
Given G(s) =
∠(G(ωpc)) = 900 – 0.5 tan-1pc) – 4 tan-1pc) = -1800
By solving we get ωpc = √3 rad/sec
