摘要：
This brief studies the synchronization control for the fractional-order chaotic system subject to input saturation and external unknown disturbances. To handle unknown disturbances, a disturbance observer is designed for the fractional-order chaotic system. A disturbance-observer-based synchronization control scheme is then developed. Under the synchronization control, the asymptotically convergent synchronization errors between two fractional-order chaotic systems can be achieved. The simulation results are presented to show the effectiveness of the proposed new design approach.
