中文摘要：
基于利用线性耦合实现空间Julia集线性广义同步的研究成果，本文通过应用非线性反馈控制和引入变量变换的方法解决了空间Julia集的非线性广义同步问题．首先基于变量变换，得到误差空间Julia系统，为了镇定该系统使其实现非线性广义同步，给出了确定的非线性函数关系式．另外，根据空间Julia集的稳定区域，解析地确定了实现非线性广义同步的耦合强度的稳定域．然后，给出了稳定的复不动平面与空间Julia集的同步的关系．最后，用一个例子验证了该解析方法是可行的．
英文摘要：
Referring to the realization of linear generalized synchronization for spatial Julia sets using linear coupling, we deal with its nonlinear generalized synchronization by applying nonlinear feedback control and introducing a multivariable transform in this work. Based on this multi-variable transform, the error spatial Julia system is obtained and the nonlinear function is given to stabilize the error spatial Julia system such that the generalized synchronization will be achieved. Moreover, according to the stability domains given for spatial Julia sets, we determine analytically the stability domain of the coupling strength for the generalized synchronization. Then, the relationship between the complex stable fixed plane and the synchronization of the spatial Julia sets is also analyzed. Finally, an example is presented to validate the scheme and the analysis.
