我们考虑一个网络化的控制系统，其中控制器必须通过一个物理网络与传感器和执行器的工厂进行通信，与输入和输出相比，通信信道较少。为了处理这样的系统，通常定义周期性通信策略，指定在任何给定时间连接哪些传感器和致动器。这项工作考虑的情况下，切换到网络的物理访问的行为需要有限的时间，在此期间，没有信息可以发送。我们考虑单输入，单输出和多输入，多输出，线性，时不变的植物和确定条件下，这些切换延迟导致系统失去的可达性和可观测性的属性。
We consider a networked control system in which the controller must communicate with the sensors and actuators of the plant through a physical network with fewer communication channels than inputs and outputs. To handle such a system, one typically defines a periodic communication policy specifying which sensors and actuators are connected at any given time. This work considers the situation where the act of switching the physical access to the network takes a finite amount of time, during which no information can be sent. We consider both single-input, single-output and multiple-input, multiple-output, linear, time-invariant plants and determine conditions under which these switching delays cause the system to lose the properties of reachability and observability.
