Control and Synchronization of Chaotic and Hyperchaotic Lorenz Systems via Extended Backstepping Techniques

Figure 10

Error dynamics between the two hyperchaotic Lorenz systems with the controller deactivated for 0<𝑡<50 and activated for𝑡≥50. The parameters of the system are as shown in Figure 2 with 𝜀_𝑖=0.3, where 𝑖=1,2,3,4.
