事件触发的控件包括在满足预定义的状态依赖性标准时关闭反馈循环。与传统的周期性实施相比，该范式特别适合嵌入式系统和网络控制系统，因为它能够减少控制所需的通信和计算资源的量。在本文中，我们提出了一个使用混合系统工具对非线性系统进行事件触发的稳定框架的框架，该工具足以包含大多数现有事件触发的控制技术，我们将重新审视和推广。我们还得出了两个新的事件触发条件，与文献中的可用策略相比，这可能会进一步扩大事件间的时间，如两个物理示例所示。这些新颖的技术体现了引入其他变量以设计触发定律的相关性。拟议的方法以及新的事件触发策略是灵活的，我们认为它们可用于解决其他基于事件的控制问题。
Event-triggered control consists of closing the feedback loop whenever a predefined state-dependent criterion is satisfied. This paradigm is especially well suited for embedded systems and networked control systems since it is able to reduce the amount of communication and computation resources needed for control, compared to the traditional periodic implementation. In this paper, we propose a framework for the event-triggered stabilization of nonlinear systems using hybrid systems tools, that is general enough to encompass most of the existing event-triggered control techniques, which we revisit and generalize. We also derive two new event-triggering conditions which may further enlarge the inter-event times compared to the available policies in the literature as illustrated by two physical examples. These novel techniques exemplify the relevance of introducing additional variables for the design of the triggering law. The proposed approach as well as the new event-triggering strategies are flexible and we believe that they can be used to address other event-based control problems.
