| Abstract: |
| In this article,the hybrid projective synchronization(HPS)of a class of chaotic (or hyperchaotic)systems with uncertain parameters is studied.Based on the adaptive technique and Lyapunov stability theory,a general scheme is developed for realizing the HPS between two chaotic(or hyperchaotic)systems with identical or different structures in any scaling factor.Finally,some numerical simulations are provided to demonstrate the effectiveness and robustness of the proposed scheme. |
