This occurs over the frequency range during which the slope of the magnitude curve on the bode plot is truly -20dB/decade. The -20dB/ decade slope will start to become steeper than -20dB/decade from about a decade below that double pole.
WebOct 23, 2024 · Making Nyquist Plots The Nyquist plot is a plot in the complex plane of Re(H(s)) and IM(H(s)) for sj as goes from zero to infinity. As such it captures in a single plot the two Bode plots of magnitude and phase versus . The Nyquist plot is easily drawn from the Bode magnitude and phase plots. Nyquist Plots of Compensators WebNyquist plots are the continuation of polar plots for finding the stability of the closed loop control systems by varying ω from −∞ to ∞. That means, Nyquist plots are used to draw the complete frequency response of the open loop transfer function.
