Model modification and feature study of Duffing oscillator
Journal of Low Frequency Noise, Vibration and Active Control, 2022 With the development of chaos theory, Duffing oscillator has been extensively studied in many fields, especially in electronic signal processing. As a nonlinear oscillator, Duffing oscillator is more complicated in terms of equations or circuit analysis.

Detection of coupling in Duffing oscillator systems [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2021 In complex dynamical systems, the detection of coupling and its direction from observed time series is a challenging task. We study coupling in coupled Duffing oscillator systems in regular and chaotic dynamical regimes. By observing the conditional mutual information (CMI) based on the Shannon entropy, we successfully infer the direction of coupling ...
