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

Figure 8

Bifurcation diagram showing the coordinate 𝑥₁ (a) and 𝑥₂ (b) of the Poincaré section versus the amplitude of driving force. The frequency of driving force is 1.325 and the initial conditions are 𝑥₁(0)=1, 𝑥̇₁(0)=0, 𝑥₂(0)=0, 𝑥̇₂(0)=0 with other parameters are 𝑐₁=𝑐₂=0.1, 𝑘₃=1, and 𝑘_𝑐=5.
