Basin analysis of system (14) forc= 0.048. The basins of attraction are shown in grey for equilibrium (x₂,0) and in green for equilibrium (x₃,0). The yellow dots denote points (x₂,0) and (x₃,0), while the black dots indicate equilibrium (x₁,0). (a)α= 0.4 and (b)α= 0 for belt velocityv₀= 0.2. (c)α= 0.4 and (d)α= 0 for belt velocityv₀= 1. (e)α= 0.4 and (f)α= 0 for system (14) with no friction (μ= 0).
