Synchronization of Hyperchaotic System Based on Fuzzy Model and Its Application in Secure Communication

The synchronization of hyperchaotic Lorenz system based on TS fuzzy model is studied. Based on Lyapunov stabilization theory, the Lyapunov function is constructed, and the synchronization control is realized with parallel connection method when the parameters of the system are known. The secure communication scheme is designed according to the synchronous system and its application in secure communication of hyperchaotic synchronization is analyzed with the method of chaotic masking. The numerical simulation results prove the feasibility and effectiveness of the proposed scheme.
