Abstract:

Using the stability theory of fractional calculus, the paper proposes a new control method for the synchronization of the fractionalorder hyperchaotic system. In the paper, the synchronization between two identical fractionalorder Chen hyperchaotic systems is realized by designing only two suitable controllers in the response system. Furthermore, this control scheme can be used in secure communication via the technology of chaotic masking using the complex nonperiodic information as trial message, and the useful information can be recovered at the receiver. Numerical simulations coincide with the theoretical analysis results, demonstrating the effectiveness and feasibility of the proposed method.
