This paper mainly investigates finite-time synchronization control of chaotic systems with multi-switching mode.For multiple real chaotic systems with different orders,its multi-switching synchronization behavior is investigated and finite-time combination multi-switching synchronization is defined,and a class of finite-time control schemes is designed,which can realize fast synchronization,when sufficient conditions for finite-time stability of error systems are provided.Finally,simulation results show that the proposed control scheme has fast convergence and reasonable validity.
