Figure 4. (a) Periodic motion and quasiperiodic motion at initial conditions [0.8, 0] (purple) and [0.3, 0] (green). (b) Enlarged view of the phase plot of quasiperiodic motion. Also shown are time series plots of (c) periodic motion in purple and (d) quasiperiodic motion in green for f0 = 0.02, Ω = 0.05 with q = 0.5, α = 1.5, β = 0.2, l = 0.3, k = 0.3 and v = 0.2.
