For the purposes of demonstration, all calculated poles (both consistent and computational) are included in the plots. As can be observed, though clearly present throughout the frequency range (Figure 1), the non-realistic, computational poles, are not observed in the vicinity of the S-domain computed pole clusters (Figures 2, 3 and 4.) 0 500 1000 1500 2000 2500 0 0.2 0.4 0.6 0.8 1 1.2 Pole Surface Consistency Imaginary (Hz) Zeta (%) cluster pole & vector pole frequency conjugate non realistic 1/condition Figure 2.
