Abstract:

In this paper, a new financial Duffing-Holms chaotic model is proposed, and the basic dynamical properties of the system are discussed, such as Hopf bifurcation, dissipation, Lyapunov exponent, Poincar\'{e} diagram and bifurcation diagram. A new finite-time convergence theorem is proposed for general chaotic systems. Compared with the existing finite-time control of chaotic systems, the new finite-time controller with fractional index greater than 1 can also realize the finite-time synchronization of financial Duffing-Holms chaotic systems. The validity of the theoretical results is verified by numerical simulation.

Key words: Duffing-Holms model, chaotic system, finite-time synchronization, chaos control, dynamics
