A New Fractional-Order Chaotic Complex System and Its Antisynchronization

Abstract EN

We propose a new fractional-order chaotic complex system and study its dynamical properties including symmetry, equilibria and their stability, and chaotic attractors.

Chaotic behavior is verifiedwith phase portraits, bifurcation diagrams, the histories, and the largest Lyapunov exponents.

And we find that chaos exists in this system with orders less than 5 by numerical simulation.

Additionally, antisynchronization of different fractional-order chaotic complex systems is considered based on the stability theory of fractional-order systems.

This new system and the fractional-order complex Lorenz system can achieve antisynchronization.

Corresponding numerical simulations show the effectiveness and feasibility of the scheme.
