摘要
通过使用受限等价变换,研究了广义动态系统观测器的构造问题,提出了观测器参数化新的表达形式,并分析了其结构机理,最后给出了一个数值例子.得到的观测器参数化结果可用于解决广义动态系统最优H2/H∞滤波问题以及鲁棒观测器的设计问题.已知的正常系统的相应结果可以作为本文结果的特殊形式.
The construction of linear observers of a generalized dynamical systems is investigated by using the restrictive equivalent transformation. A new parameterization of all normal observers is presented. The mechanism of the derived observer is also analyzed. A numerical example is given to illustrate the design procedure. The developed results can be utilized to solve the design problems such as H_2/H_∞ filtering, robust estimation and fault detection,etc. The known result of the normal systems can be regarded as a particular form of our parameterization.
