摘要:

本文研究了在时变速率限制通信信道上线性时不变系统事件触发稳定化问题。我们明确考虑了信道断连的可能性,即通信信道在反馈过程中不可用的时间间隔。假设已知信道演变信息,我们研究信道容量,即给定时间间隔内可传输的最大总比特数,并提供一种高效的实时算法来对确定性时间分槽信道演变模型的信道容量进行下界估计。基于这些结果,我们设计了一种事件触发策略,该策略在存在间歇性信道断连的情况下,能够保证无Zeno行为和指数稳定化,即使在期望的收敛速率下。贡献包括信道断连的概念、在存在这些断连时的有效事件触发控制,以及对一类时变连续时间信道的信道容量分析和量化。各种仿真示例展示了结果。

英文摘要:

This paper studies event-triggered stabilization of linear time-invariant systems over time-varying rate-limited communication channels. We explicitly account for the possibility of channel blackouts, i.e., intervals of time when the communication channel is unavailable for feedback. Assuming prior knowledge of the channel evolution, we study the data capacity, which is the maximum total number of bits that could be communicated over a given time interval, and provide an efficient real-time algorithm to lower bound it for a deterministic time-slotted model of channel evolution. Building on these results, we design an event-triggering strategy that guarantees Zeno-free, exponential stabilization at a desired convergence rate even in the presence of intermittent channel blackouts. The contributions are the notion of channel blackouts, the effective event-triggered control despite their occurrence, and the analysis and quantification of the data capacity for a class of time-varying continuous-time channels. Various simulations illustrate the results.
