摘要
本文研究了多切换模式下混沌系统的有限时同步控制问题.针对多个不同阶实变量混沌系统,研究了其多切换同步行为,给出了有限时多切换组合同步的定义,进而,在给出误差系统的基础上,设计了一类实现快速同步的有限时控制方案,并给出了误差系统有限时稳定的充分条件.最后,仿真结果表明所设计控制方案具有快速收敛性,较好地验证了有效性.
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.
