| Abstract: | Based on adaptive control method and Lyapunov stability theory respectively in the cases of fully and partly unknown parameters, nonlinear adaptive control laws are designed so that the hyperchaotic Lu systems are generalized projective synchronization. Finally, numerical simulations are given to demonstrate the two identical hyperchaotic Lu systems are globally asymptotically generalized projective synchronization. Furthermore, the tracking of parameters in the later case is realized. |
