| Abstract: | In this paper, based on state observer, the synchronization of a class of hyperchaotic system and its application to secure communication are considered in the presence of perturbation. The result shows that the proposed method can overcome the perturbations influence on synchronization of hyperchaotic system, and make the system keep synchronous well. Meanwhile, the considered sysem is hyperchaotic that means the communication system is more secure. Therefore, the proposed method is more feasible in practical communication application. |
