Abstract: The author considered finitetime synchronization of  fractionalorder uncertain Like-Bao system. According to the fractional order finitetime synchronization theory, the author gave sufficient conditions for Like-Bao systems to achieve finitetime synchronization. The results show that the driveresponse systems of fractionalorder uncertain Likebao chaotic systems are finitetime synchronization under certain conditions.

Key words: fractionalorder, Like-Bao chaotic system, finitetime, synchronization
