Generalized projective synchronization of two four-dimensional chaotic systems
两个四维混沌系统广义投影同步

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.
