This paper studies the dynamic event-triggered intermittent control (D-ETIC) for the stabilization of delayed dynamical systems (DDS). The stabilization of DDS via general intermittent control is formulated as a problem of delay-dependent minimal activation time rate (MATR). A D-ETIC scheme with input delay is proposed to stabilize DDS. The delay-dependent MATR is estimated. And the maximal input delay allowed in D-ETIC is estimated for quasi-linear DDS. Both theoretical and numerical comparisons are given among D-ETIC, static ETIC (S-ETIC), and the recently developed static intermittent control schemes, including time-triggered intermittent control and event-triggered aperiodic intermittent control. It is shown that the proposed D-ETIC achieves the lowest MATR. It is also shown that larger delays, including the time delay in DDS and the input delay in D-ETIC, may lead to more control activation time for the stabilization.

用于稳定延迟动力系统的动态事件触发间歇控制

本文研究了动态事件触发间歇控制 (D-ETIC) 以稳定延迟动力系统 (DDS)。通过一般间歇控制实现 DDS 的稳定性被表述为延迟相关最小激活时间率 (MATR) 的问题。提出了一种具有输入延迟的 D-ETIC 方案来稳定 DDS。估计延迟相关的 MATR。并且为准线性 DDS 估计了 D-ETIC 中允许的最大输入延迟。对 D-ETIC、静态 ETIC (S-ETIC) 和最近开发的静态间歇控制方案(包括时间触发间歇控制和事件触发非周期间歇控制)进行了理论和数值比较。结果表明,所提出的 D-ETIC 实现了最低的 MATR。它还表明,较大的延迟,
