Computer Simulation of Coupled Synchronized the Rikitake Chaotic Systems

In this paper, the chaos and chaos synchronism of the Rikitake two-disk dynamo are studied further, not only numerical simulation, but circuit realization. The coupled synchronism method is used to synchronize two identical Rikitake systems with two significantly different initial conditions. The sufficient condition of global asymptotic synchronization is attained from the theory of Lyapunov stability. Numerical simulations shows the effectiveness and feasibility of this method in synchronizing two coupled Rikitake systems, and the method has some more advantageous and succinct excellence than others.
