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

Figure 3

The frequency-amplitude curves of the system when the van der Pol oscillator is strongly coupled to the Duffing resonator. The parameters are, respectively, 𝑐₁=0.1, 𝑐₂=0.05, 𝑘₃=0.3, 𝑘_𝑐=8, and 𝑓_𝑑=0.2.
