网络控制系统(NCS)通常由一组控制器和传感器组成，这些控制器和传感器可以通过支持有限数量连接的网络连接到工厂。通信策略确定何时切换不同控制器、传感器和工厂之间的连接。在这项工作中，我们考虑这样的场景，其中每个交换机需要有限的时间来完成；在此期间没有活动的连接。我们建立了单输入单输出系统保持能观性和能达性的条件，并给出了详细的结果。
A networked control system (NCS) typically consists of a collection of controllers and sensors that can be connected to a plant across a network that supports a limited number of connections. A communication policy determines when to switch the connections between the different controllers, sensors and the plant. In this work we consider the scenario where each switch takes a finite amount of time to complete; during this time there are no active connections. We establish conditions under which the properties of observability and reachability are maintained and present detailed results for single-input, single-output systems.
