摘要

本文研究了非线性系统的安全临界事件触发控制（ETC）。它提出了一种新的 ETC 策略，通过使用可调整的输入到状态安全屏障函数来确保事件触发的安全性。然后，通过构建合适的动态事件触发机制，设计了一种有效节省通信资源和减少计算负荷的方法。此外，还保证了闭环系统排除 Zeno 行为。最后，本文通过两个示例展示了所提控制策略的有效性。

Safety-critical event-triggered control of nonlinear systems with tunable input-to-state safe barrier functions

This paper investigates safety-critical event-triggered control (ETC) for nonlinear systems. It proposes a new ETC strategy that ensures event-triggered safety by using a tunable input-to-state safe barrier function. Then, a method is devised to effectively save communication resources and reduce computational load through the construction of a suitable dynamic event-triggered mechanism. Furthermore, the exclusion of Zeno behavior is guaranteed for the closed-loop system. Finally, this paper culminates by presenting two illustrative examples that showcase the effectiveness of proposed control strategies.
