Anticipating synchronization of the fractional-order system via nonlinear observer

In this paper, we assess anticipating synchronization of chaotic fractional system with commensurate order. Based on stability theory of linear fractional order systems, an approach for constructing anticipating synchronization of fractional order systems is proposed. This technique is applied to achieve the anticipating synchronization of fractional-order Roumlssler's system, verified by numerical simulation.
