Abstract: We studied adaptive sliding mode synchronization of variable fractional-order Sprott-R chaotic system. Based on variable fractional-order Lyapunov stability theory, we applied finite-time synchronization related conclusions and designed a variable fractional-order finite-time adaptive sliding mode controller to obtain the synchronization conditions of variable fractional-order Sprott-R chaotic system under certain assumptions. We then used MATLAB for number simulation to verify the conclusion.

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