摘　　要：在符号动力学的基础上,提出了全局耦合映像格子系统的初始状态估计算法。在理论上,系统分析了全局耦合映像系统初始状态估计的收敛条件及其估计性能与系统参数之间的数学关系。在满足收敛性要求的参数条件下,即使映像过程受到高斯白噪声的污染,该算法依然能够很好地估计出系统的初始状态,为更好地分析实际模型的物理过程提供了理论依据与实验结果。An initial condition estimation algorithm for global coupled map lattice systems based on the symbolic sequence is proposed. The convergent condition for estimating initial condition and the relationship between estimation performances and system parameters are theoretically analyzed. When the parameters meet the requirement of astringency, even if the mapping process is contaminated by white Gaussian noises, the initial condition can still be estimated perfectly by the presented algorithm. This investigation provides a theoretical and practical basis for a better analysis and description of the physical process of the actual model.
