Abstract: By using sliding mode synchronization theory and sliding mode dynamic methods, we studied sliding mode synchronization 
of fractional-order Rikitake uncertain chaotic systems and drew the attractor phase diagrams of Rikitake chaotic systems. According to fractional-order calculus, we constructed three sliding mode functions, gave three synchronization schemes, and compared and analyzed three synchronization schemes. The results show that fractional-order Rikitake uncertain chaotic system can achieve sliding mode synchronization under certain conditions.

Key words: fractional-order, sliding mode, synchronization, chaotic system
