Prefilter Bode Diagram

The prefilter Bode diagram displays magnitude and phase plots for your system.

Bode Magnitude Plot

The Bode magnitude diagram displays two curves:

• The green curve represents the prefilter Bode magnitude
• The magenta curve displays the Bode magnitude response of the closed-loop system, from command r to output y. This figure shows the path from command r to output y.
  
  

Grab the green curve with your mouse and drag it up and down to adjust the prefilter gain. Use the right-click menu to add dynamics to the prefilter.

Bode Phase Plot

The Bode phase diagram also displays two curves. The green curve represents the prefilter Bode phase The magenta curve displays the closed-loop Bode phase response from command r to output y, as shown in the figure above.
