Coupled Oscillator Bifurcation

Two van der Pol oscillators coupled bidirectionally — explore Hopf bifurcations in phase space


Parameters

Limit Cycle
Van der Pol coupling:
ẍ₁ - μ(1-x₁²)ẋ₁ + ω₁²x₁ = k(x₂-x₁)
ẍ₂ - μ(1-x₂²)ẋ₂ + ω₂²x₂ = k(x₁-x₂)

μ<0: stable fixed point
μ=0: Hopf bifurcation
μ>0: limit cycle attractor
