摘要

本研究探讨了部分未知逗留概率信息下切换系统的基于观测器的控制。为了更准确地捕捉切换系统的动态特性，设计了一种与持续时间相关的切换规则，其中系统切换由联合分布函数控制。该功能独特地集成了当前系统模式和持续时间，有效地解决了概率信息不完整的挑战。与传统的半马尔可夫核技术不同，逗留概率涉及较少的参数，并且可以更容易地使用统计技术进行测量，从而减少了计算负担。另外，构造了一个非单调Lyapunov函数，得到了保证切换系统均方稳定性的较小保守条件。最后，通过实例验证了所设计方法的有效性和优越性。

A novel switching rule to observer-based control for switched systems

This study explores observer-based control for switched systems subject to partially unknown sojourn probability information. To more accurately capture the dynamic nature of switched systems, a novel switching rule related to duration time is devised, in which the system switching is governed by a joint distribution function. This function uniquely integrates both the current system mode and its duration, effectively addressing the challenges of incompleteness in probability information. Distinct from the conventional semi-Markov kernel technique, the sojourn probabilities involve fewer parameters and can be more readily measured using statistical techniques, thereby lessening computational burden. Additionally, a non-monotonic Lyapunov function is constructed, leading to less conservative conditions that ensure the mean-square stability of the switched systems. Eventually, the effectiveness and superiority of the devised methodology are verified through a practical example.

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.
