Impulsive Perturbations of a Three-Species Food Chain System with the Beddington-DeAngelis Functional Response

Figure 3

The dynamical behavior of the system (1.1). (a)–(c) show that a trajectory with a starting point (𝑥₀,𝑦₀,𝑧₀)=(10,1,0.4) approaches the periodic orbit (𝑥^∗(𝑡),0,𝑧^∗(𝑡)). In (d)–(f), the behavior of trajectory with a different starting point (𝑥₀,𝑦₀,𝑧₀)=(100,100,100) is shown.
