本文定义了偏微分方程部分能观性的一个定量度量。如果使用适定逼近方案来逼近偏微分方程,则证明该量是一致的。一阶近似的不可观测性指数使用经验Gramian的介绍。给出了几个例子来说明部分可观性的概念。该理论是为初始值的估计而发展的。然而,这个概念可以扩展到状态变量在最终时刻或任何固定时刻的可观测性。
In this paper, a quantitative measure of partial observability is defined for PDEs. The quantity is proved to be consistent if the PDE is approximated using well-posed approximation schemes. A first order approximation of an unobservability index using an empirical Gramian is introduced. Several examples are presented to illustrate the concept of partial observability. The theory is developed for the estimation of initial value. However, the concept can be extended to the observability of state variables at final time or any fixed time moment.
