This paper proposes a new discretization model for Duffing oscillator dynamics which is governed by a second order nonlinear differential equation. A Taylor-Lie formulation based method has been used ...

The existing Duffing oscillator weak signal detection method will lead to the degradation of detection performance when the noise is strong. In order to reduce detection signal-to-noise ratio and ...

The Jupyter notebook file diff_eq_plot.ipynb includes the code for numerically solving the Duffing equation (Eq. 30 in the paper) using RK4, the following Fourier analysis, and plotting the figures in ...
