两个四维混沌系统广义投影同步

Generalized projective synchronization of two four-dimensional chaotic systems

利用主动控制同步法设计合适的非线性反馈控制器,实现两个相同的四维混沌系统的同结构广义投影同步,以及实现两个不同的新型四维混沌系统异结构广义投影同步.通过改变广义投影同步的比例因子,获得任意比例于原驱动混沌系统输出的混沌信号.数值仿真表明了所设计的控制器有效性和理论推导的正确性.

In this paper,the generalized projective synchronization has been observed in the coupled four-dimensional chaotic systems.The different nonlinear feedback controllers are designed by an active control method for synchronization of two chaotic systems with the same or different structures.The proposed technique allows us to arbitrarily direct the scaling factor to a desired value.Numerical simulation is provided to show the effectiveness of the theoretical analysis.
