中文摘要

      本文利用最优状态估计理论，讨论了二维线性离散系统一般模型（2-D General Model，简称2-D GM）最优状态估计问题. 基于2-D GM的变结构1-D表示，导出了表现为1-D形式的2D GM的最优状态估计器. 文中还直接由2-D GM出发，将1-D最优状态估计的思想推广到2-D情形，提出了2-D状态估计器的设计方法.

英文摘要

      By using the existing optimal state estimation the. ory， the problem of optimal state estimation for two-dimensional (2-D) linear discrete systems has been discussed in this paper. On the basis of its reduc-tion t0 1-D systems with variable structure， the l-D optimal state estimators for 2-D general modeI(GM) have been inferred. Furthermore， the approach for designing the 2-D state estimator has been directly produced from 2-D GM by extending the l-D results t0 2-D setting.
