| 中文摘要 |
| 本文考虑具有随机观测时滞系统的后退时域估计问题. 首先, 针对随机时滞网络控制系统, 运用观测重组技术,
将带有时滞的观测方程转化为无时滞观测方程, 得到一组新的无时滞观测序列. 在此基础上, 运用线性最小方差无偏估
计理论, 推导出后退时域估计器的批形式公式和迭代形式公式, 并给出稳定性分析. 通过具体的仿真实例, 对比现有卡
尔曼滤波器, 验证了所提出的后退时域估计器具有更好的跟踪能力. |
| 英文摘要 |
| This paper is concerned with the receding horizon estimation problem for discrete -time systems with random
delayed observations. Firstly, the random delay system is reconstructed as an equivalent delay-free one by measurement
reorganization technique. Secondly, a batch form and a recursive form for receding horizon estimation are proposed on the
basis of the new changed system and by minimizing a new cost function that includes two terminal weighting terms. Then
based on the derived condition, the stability of the proposed receding horizon estimation is proved. Finally, a numerical
example is given for illustration. |
