本文,将符号动力学推广到耦合映像格子中,以Logistic映射下耦合映像格子为研究对象,研究控制参数对符号向量序列动力学特性的影响.通过研究耦合映像格子逆函数,给出耦合映像格子的遍历条件.进一步,将给出系统初始向量,禁止字以及控制参数的符号向量序列描述方法,并最终给出基于符号向量动力学的耦合映像格子控制参数估计方法.实验结果表明,根据本文算法可以有效建立符号序列和耦合映像格子控制参数之间的对应关系,能够更好地刻画了实际模型的物理过程.
In this paper, we introduce the symbolic dynamics into the coupled map lattice and study the influence of the control parameters on the dynamical properties of the symbolic vector sequence with the coupled map lattice under the Logistic map. By studying the coupled map lattice inverse function, We will give a description of the sequence vector of initial vectors, forbidden words and control parameters of the system, and finally give a method of parameter estimation of the coupled map lattice control based on the symbol vector dynamics.The experimental results show that according to the algorithm Can effectively establish the corresponding relationship between the symbol sequence and the coupled map lattice control parameters, and can better depict the physical process of the actual model.
