Abstract

This study investigates different observer architectures for the state estimation of linear aperiodic sampled-data systems and formally shows that a complex structure is not necessarily better than a simpler one with respect to the considered cost functional and to a class of timer-dependent Lyapunov functions. The work also shows how to design the state observer through sum of squares programming, presenting a numerical example.

非周期性测量的观测者：越简单越好？

本研究探讨了用于线性非周期性采样数据系统状态估计的不同观测器结构，并正式表明，就所考虑的成本函数和一类依赖计时器的 Lyapunov 函数而言，复杂结构并不一定比简单结构更好。该研究还展示了如何通过平方和编程设计状态观测器，并提供了一个数值示例。

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.
