bode plot of simulink model using matab commands (codes)

Hi there,

I have modeled a transfer function in Simulink. How can I get the bode plot of the model using Matlab code? I don't want to use the model linearizer in the apps.

Thanks

Hi @Mahdi Zolfaghari

This is an example to get the Bode plot with MATLAB code:

Gp = tf([1 3], [1 2 3 0])

Gp =
 
        s + 3
  -----------------
  s^3 + 2 s^2 + 3 s
 
Continuous-time transfer function.

bode(Gp)

margin(Gp)  % if you want to display the stability margins
