Predefined time projective synchronization control of Lorenz chaotic systems

This article devotes to the predefined time projective synchronization of two coupled Lorenz chaotic systems. Firstly, the predefined time stability theorem of reference [27] is applied to the synchronization of chaotic systems, which can achieve faster convergence speed. Then the predefined time synchronization of chaotic systems under different projective factors is proved. Finally, several numerical simulations are presented to show the effectiveness of the proposed methods.
