Abstract For a spectrally observable delay system with one-dimensional output, we construct a differential-difference finite time observer, i.e., an estimation system whose output, starting from a certain time moment, is identically equal to the solution of the original system. The results are illustrated by an example.

一维输出延迟系统的微分差分观测器

摘要 对于具有一维输出的谱可观测延迟系统，我们构造了一个微分差分有限时间观测器，即一个估计系统，其输出从某一时刻开始，与原系统的解完全相等。结果通过一个例子来说明。
