时滞非线性系统的动态自触发控制

Dynamic self-triggered control for nonlinear systems with delays

Michael Hertneck, Frank Allgöwer

摘要:

自触发控制是网络控制系统确定采样时刻的一种资源有效的方法。最近,Hertneck和Allgöwer(2021 b)提出了一种基于混合李雅普诺夫函数的非线性NCS动态STC策略,但仅限于无传输延迟的NCS。在本文中,我们扩展了这种策略的非线性网络控制系统的传输延迟。处理具有延迟的系统的能力使得可以在不能保证无延迟的即时传输的许多实际场景中使用所得到的动态STC机制。建议的动态STC机制保证稳定,尽管有界的传输延迟。该机制的有效性说明了一个数值例子,并比较国家的最先进的文献。

英文摘要:

Self-triggered control (STC) is a resource efficient approach to determine sampling instants for Networked Control Systems (NCS). Recently, a dynamic STC strategy based on hybrid Lyapunov functions for nonlinear NCS has been proposed in Hertneck and Allgöwer (2021b), however with the limitation to NCS without transmission delays. In this paper, we extend this strategy for nonlinear NCS with transmission delays. The capability to handle systems with delays makes it possible to use the resulting dynamic STC mechanism in many practical scenarios where instant transmissions without delays cannot be guaranteed. The proposed dynamic STC mechanism guarantees stability despite bounded transmission delays. The effectiveness of the mechanism is illustrated with a numerical example and compared to state-of-the art literature.
