Nyquist Diagram an overview ScienceDirect Topics

The conventional Nyquist diagram must be modified to apply the Nyquist stability criteria to the frequency-response plot. In a linear system, the crucial point on the Nyquist diagram is −1. For nonlinear systems the −[1/ N(ω, X)] locus corresponds to the critical point −1.To evaluate the stability of the system, both −[1/N(ω, X)] and the G(jω) function are plotted on the polar plane.
