Multistability of Globally Coupled Duffing Oscillators [PDF]
International Journal of Bifurcation and Chaos, 2021 We analyze the collective dynamics of an ensemble of globally coupled, externally forced, identical mechanical oscillators with cubic nonlinearity. Focus is put on solutions where the ensemble splits into two internally synchronized clusters, as a consequence of the bistability of individual oscillators. The multiplicity of these solutions, induced by

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.
