与口语中使用停顿来传达信息的方式类似，在通信网络中不仅可以通过消息内容，还可以通过其时间来传输信息。本文提出了一种事件触发策略，该策略通过以状态相关的方式传输来利用定时信息。我们考虑了数字通信通道上连续时间、时不变、线性对象的稳定性，具有有限延迟并受到有限对象扰动，并建立了两个主要结果。一方面，我们设计了一种编码-解码方案，保证足够的信息传输速率以实现稳定。另一方面，我们确定任何控制政策稳定所需的信息传输速率的下限。
Similar to the way pauses are used in spoken language to convey information, it is also possible to transmit information in communication networks not only by message content, but also with its timing. This article presents an event-triggering strategy that utilizes timing information by transmitting in a state-dependent fashion. We consider the stabilization of a continuous-time, time-invariant, linear plant over a digital communication channel with bounded delay and subject to bounded plant disturbances, and establish two main results. On the one hand, we design an encoding–decoding scheme that guarantees a sufficient information transmission rate for stabilization. On the other hand, we determine a lower bound on the information transmission rate necessary for stabilization by any control policy.
