For many unknown (or complex) systems this is a very common method for determining the transfer function.

(There’s nothing magic about using the spline.

Bode Plot and resonant peaks. The Nyquist plot is a closed curve that describes a graph of KGH(jω) for ω ∈ ( − ∞, ∞). The peaks in the magnitude plot show that the first resonant frequency is at 910 Hz, and the second resonant frequency is at.

), and then decreases 20 dB for every factor of ten increase in frequency (slope = -20 dB/decade). b = 2e9; a = conv([10 1],[1e5 2e9]); sys = tf(b,a); bode(sys); If you want to do it from scratch, you can create a vector of frequencies and plot the function against them.

Frequency is the logarithmic axis on both plots. [2, 25] Range: 0 250 or 4 cycles 0 : 1000 Damping factor=0.

This is the closes as I can get the ideal bode plot. Setting the phase matching options so that at 1 rad/s the phase is near 150 degrees yields the second Bode plot. This is commonly referred to as the “crossover frequency”.

You can compute the resonance frequency Wr by differentiating w.
