Projective Synchronization of a Five-term Hyperbolic-type Chaotic System Based on One Driving Signal

  • 摘要: 针对最新提出的五项双曲线混沌系统,基于李亚普诺夫稳定性原理,采用常数和混沌系统变量作为比例因子,分别研究了两个初值不同的系统之间的广义投影同步与函数投影同步.根据推导的单驱动变量投影同步定理,设计了相应的同步控制器,并研究了控制参数的范围;讨论了控制参数的大小与混沌同步系统性能之间的关系.数值仿真表明了该同步方法的有效性.

     

    Abstract: The projective synchronization between two chaotic systems with different initial values is investigated based on Lyapunov stability theory in the five-term hyperbolic-type chaotic systems proposed recently. Using constants and variables as scale factor chaotic systems, two schemes of projective synchronization are established, namely generalized projective synchronization and function projective synchronization. In accordance with the deduced single driving variable projective synchronization theory, the corresponding synchronization controller is designed, and the range of control parameters is determined. The relationship between the control parameters and chaotic synchronization performances is discussed. Simulation results show the effectiveness of the methods.
