在这篇笔记中,我们提出了一种替代的线性系统的功能可观性的特征。主要特点是得到了定常线性系统存在稳定多功能观测器的充分必要条件。这个条件的证明是建设性的,它导致设计一个稳定的观察员通过一个新的程序,既不基于解决方案的西尔维斯特方程,也不使用规范的状态空间形式。
In this note, we propose an alternative to characterize the functional observability for linear systems. The main feature is that we obtain a necessary and sufficient condition for the existence of a stable multi-functional observer of a time-invariant linear system. The proof of this condition is constructive and it leads to design a stable observer via a new procedure, neither based on the solution of a Sylvester equation nor on the use of canonical state space forms.
