Abstract :
In this paper, for a three dimensions autonomous continuous nonlinear dynamical system, the chaotic characteristic and control of chaotic synchronization of model of fractional-order are researched by the theory of fractional-order calculus. The results show that the lowest order of which chaos can occur is 0.855 in this nonlinear dynamic model of fractional-order. Based on the theory of stability of the fractional-order dynamical system, the controller is designed, the control of chaotic synchronization of nonlinear dynamic model of fractional-order is implement and the chaotic synchronization is proved analytically. Finally, the validity of nonlinear controller designed in this paper is verified by numerical simulation using Adams-Bashforth-Moulton arithmetic.
