摘要

针对一类具有严格前馈形式和多时滞的随机非线性系统，研究了一种新的输出反馈控制策略。首先给出了系统的参数依赖观测器和输出反馈控制器。然后，通过引入相应的参数相关坐标变换，得到原系统的等价形式。最后，利用随机非线性时滞系统的稳定性理论，构造合适的Lyapunov-Krasovskii泛函，验证了闭环系统的全局渐近稳定性。通过两个算例验证了理论结果。

Output feedback control of stochastic systems in strict-feedforward form with time delays

A novel output feedback control strategy for a class of stochastic nonlinear systems subject to strict-feedforward form and multiple time delays is mainly investigated in this paper. The parameter-dependent observer and output feedback controller of the studied system are firstly presented. And then, the equivalent form of the original system can be obtained via introducing the corresponding parameter-dependent coordinate transformation. Finally, the global asymptotic stability of the closed-loop system is verified by using the stability theory of stochastic nonlinear time delay systems and constructing the suitable Lyapunov–Krasovskii functional. The theoretical result is verified through two examples.

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.
