线性时变离散系统的状态观测器

State Observer of Discrete Linear Time-Varying Systems

本文放弃了Ｌｕｅｎｂｅｒｇｅｒ状态观测器理论对系统完全可观测性的要求，提出了一般线性时变离散系统的状态观测器设计方法，并对ｊ＝ｉ，ｉ－１给出了系统完全（ｉ，ｊ，Ｔｉ）－可重构这一新概念的充要条件．

A state observer design procedure is presented for discrete linear time-varying systems,without such requirement as complete observabllity in the well known Luenberger's observer theory. The necessary and sufficient condition for the new concept of complete(i,j,Ti)-reconstructibility,where j=i,i-1,is given.
