| 英文摘要 |
| In this paper, Julia and Mandelbrot sets of the two dimensional generalized real Logistic map are discussed.
Firstly, the fractal dimension of a Julia set of this real map is obtained by using the box counting dimension method, and
the control of Julia sets of this real map are accomplished by using the linear feedback control. Secondly, the concept of
synchronization of Julia sets between different systems are introduced, then the synchronization of Julia sets of two real
maps with different parameters are realized by using the nonlinear coupling control. Finally, the Mandelbrot set of this
real map is constructed by introducing real parameters, and gradient control is taken to realizing the synchronization of
Mandelbrot sets of two real maps which have different parameters. Simulation results show the effectiveness of the control
and synchronization methods. |
