摘要

本文给出了用解释Petri网建模的离散事件系统状态估计的新结果。首先，介绍了事件可探测性和事件可观测性的概念。然后给出了用标记图和状态机描述系统的可观测性的充分必要条件。最后，提出了一种通用的状态估计方案。这个结果用一个制造系统的例子来说明。

A Petri net scheme for DES state estimation

This paper presents new results on state estimation of discrete event systems modeled by interpreted Petri nets. First, the concepts of event detectability and observability are introduced. Then necessary and sufficient conditions for observability of systems described by marked graphs and state machines are presented. Finally, a general scheme for state estimation is proposed. This result is illustrated using an example of a manufacturing system.
