Multistability in a dynamical system has attracted great attention recently for its complex and unexpected states. Since in most chaotic systems coexisting attractors reside in their own individual basin of attraction with a fractal structure, it becomes a challenge to choose correct initial conditions to obtain desired dynamics. Selecting typical dynamics as the basic components in a dynamical sequence and then arranging them in the phase space in a desired order make the multistability transparent and controllable in the domain of initial conditions; thereafter, one can identify an attractor according to its initial sequence. Dynamics editing provides an effective technique to select typical attractors under different system parameters to form a flexible sequence in the phase space, which shows great potential for chaos-based secure communications.
动力系统中的多稳定性因其复杂和意外的状态而引起了极大的关注。由于在大多数混沌系统中，共存吸引子存在于它们各自具有分形结构的吸引域中，因此选择正确的初始条件以获得所需的动力学成为一项挑战。选择典型的动力学作为动力序列中的基本组件，然后按照所需的顺序在相空间中排列它们，使得在初始条件域中多稳定性变得透明和可控；此后，可以根据其初始序列识别出一个吸引子。动力学编辑提供了一种有效的技术，可以在不同的系统参数下选择典型的吸引子，以在相空间中形成灵活的序列，这在基于混沌的安全通信中显示出了巨大的潜力。
