Feedback Control in a Periodic Delay Single-Species Difference System

Figure 2

Global attractivity of system (4.1) with different initial values. 𝑥 with 𝑥(−1)=0.04, {𝑥(0),𝑢(0)}={0.0265,0.0008} and 𝑥^∗ with 𝑥^∗(−1)=0.05, {𝑥^∗(0),𝑢^∗(0)}={0.0274,0.0014}. (a) and (b) show (𝑥,𝑥^∗) for 𝑘∈[0,1000] and for 𝑘∈[980,1000], respectively. (c) and (d) show (𝑢, 𝑢^∗) for 𝑘∈[0,1000] and for 𝑘∈[980,1000], respectively.
