Application of Nyquist Plots to Stability. Choose a contour that encircles the entire right half of the s-plane. Figure Complex mapping of a closed. The Nyquist plot of a transfer function, usually the loop transfer function \$ GH(z)\$ , is a mapping of Nyquist contour in z-plane onto \$ GH(z)\$ plane which is in. Nyquist diagram: (closed) polar plot of F(jω) with ω ∈ (-с,с) we plot the magnitude and phase on the same plot using the frequency as a. Sketch the Nyquist plots for the following loop transfer functions. Find out N,P, and Z and determine if the closed loop system is stable. If yes, then for what. Why do we need to do all this work and obtain just stability results from Nyquist plots? Why not just use the Routh-Hurwitz criteria? The real value of the Nyquist.
