How can I plot a bode plot of anon linear system?

The bode plot of my non-linear system doesn't generates any response or output

[David Wilson]

Given that you have a nonlinear system, the frequency response is problematic. You could try a describing function approach.

Further details in many control textbooks such as Ogata's Modern Control Engineering.
