Abstract:

This work presents an adaptive synchronization between two different order fractional chaotic systems with unknown parameters. Based on the nonlinear feedback, the proposed adaptive scheme not only can estimate the unknown parameters successfully in certain condition, but also realize the synchronization of chaotic fractionalorder system. Taken the fractional liu system and Duffing system as an example, numerical simulation results verify the effectiveness of the proposed scheme.

Key words: parameters identification, adaptive synchronization, nonlinear feedback, fractionalorder chaos
