Nonlinear Dynamics of a Periodically Driven Duffing Resonator Coupled to a Van der Pol Oscillator

Figure 1

The frequency-amplitude curves of the system when the van der Pol oscillator is weakly coupled to the Duffing resonator. The parameters are, respectively, 𝑐₁=𝑐₂=0.001, 𝑘₃=0.003, 𝑘_𝑐=0.002, and 𝑓_𝑑=0.002.
