Abstract :
In this paper, adaptive synchronization of uncertain hyperchaotic Lorenz systems is investigated. Based on the Lyapunov stability theory, a novel nonlinear controller is designed and adaptive schemes are derived to guarantee the global asymptotical stability of the origin of considered system when the parameters of slave system are uncertain. Finally, numerical simulations are provided to show the effectiveness of proposed control design.
