Abstract: We studied adaptive sliding mode synchronization of fractional-order Sprott-F chaotic systems with uncertainties and outer disturbances. By constructing appropriate fractional-order sliding mode surfaces and control laws and adaptive rules, we obtaind two sufficient conditions for adaptive sliding mode synchronization of fractional-order Sprott-F uncertain chaotic systems. The  results show that adaptive sliding mode synchronization of
fractional-order Sprott-F uncertain chaotic systems can be  achieved under certain assumptions.

Key words: fractional-order, Sprott-F chaotic system, sliding mode, uncertain
