摘要: This paper firstly introduces the control methods to fractals and give the definition of synchronization of Julia sets between two different systems. Especially, the gradient control method is taken on the classic Julia sets of complex quadratic polynomial $z_{n+1}=z_n^2+c$, which realizes its Julia sets control and synchronization. The simulations illustrate the effectiveness of the method.
