Abstract: Based on the sliding mode method of nonlinear chaotic systems, the sliding mode control and synchronization of Sprott-D uncertain fractional-order systems were studied according to the fractional-order stability theory and synchronous control method, and the results were verified by using MATLAB simulation program. The results show that the Sprott-D uncertain fractional-order chaotic systems corresponding to the master-slave systems can achieve adaptive sliding mode synchronization under certain assumptions.

Key words: fractional-order, Sprott-D system, sliding mode, synchronization
