摘要
Li和TAO提出了化非线性系统为一种可观型的条件,用单变量积分解决了Bestle和Zeitz在非线性观测器设计中的计算问题,但是状态变量的求取比较麻烦,本文给出一个新的条件和计算方法,使非线性系统观测器的设计大为简化。
Li and TAO have given a necessary and suffcient condition under which the non-linear observer canonical form exists. By integrating single variable functions, they solved the problem of design of observer Bestle and Zeitz unsolved. But their conditions and computations of state transformation is too complex. In this paper a new existence conditions and two algorithms are given. According to this the design of non-linear observer is well simplified.
