摘要

本文提出了一种数据驱动的方法，用于设计一类具有时滞的离散大系统的控制器。在我们的工作中，我们引入了基于数据的公式来设计具有不确定时滞的离散大系统的分散状态反馈控制。这些系统可以以数据驱动的格式表示，允许使用从子系统收集的数据（如系统状态、控制输入和互连输入）对分散控制器进行参数化。利用Lyapunov-Krasovskii方法，构造了一个数据驱动的半确定规划问题，以导出分散稳定控制器。在镇定控制器设计中进一步考虑了输入数据的噪声，证明了其在不确定条件下的控制优势。

Model-free stabilization for discrete-time large-scale systems with time-delays

This paper presents a data-driven methodology for designing controllers for a specific category of discrete-time large-scale systems with time delays. In our work, we introduce data-based formulas for designing decentralized state feedback control for discrete-time large-scale systems with uncertain time delays. These systems can be represented in a data-driven format, allowing for the parametrization of decentralized controllers using data collected from subsystems, such as system state, control input, and interconnection input. By using the Lyapunov–Krasovskii method, we formulate a data-driven semi-definite programming problem to derive decentralized stabilizing controllers. The noisy input data is further considered in the stabilization controller design, demonstrating its advantage of control under uncertainties.

期刊介绍： Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field. After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience. Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
