针对复平面上有理型Julia集的控制与同步问题进行了研究。在控制方面把∞当做一个被控制的不动点,采用选择控制法来控制有理型Julia集,得到控制后的Julia集随着控制参数的增大而逐渐收缩。在同步方面采用梯度控制法来实现具有相同系统且不同参数有理型Julia集的同步,使得其中一个Julia集逐渐变化到另一个Julia集,并通过MATLAB仿真实例验证了该方法的有效性。
This paper discussed the control and synchronization for generalized Julia sets of the complex rational maps. First,it applied the optimal control function method on the Julia set of this system. This control method regarded infinity as a fixed point to be controlled. Then the controlled Julia set was shrinking with the controlled parameters. Second,it also studied synchronization for Julia sets with the same structure but different parameters. By substituting the response item for an item with the gradient control method,Julia set gradually changed to be another one. The simulations illustrate the efficacy of these methods by MATLAB.
