Abstract

The issue of reconfiguration-based fault-tolerant control for systems with actuator fault and saturation is addressed. The basic idea behind this work is to evaluate the system reconfigurability to guide the reconfiguration scheme and system structure design. First, a reconfigurability criterion is derived and utilized to quantify the degree of reconfigurability. On this basis, a passive/active combined reconfiguration method is proposed to balance the effectiveness and implementation complexity of the reconfiguration scheme. Moreover, the system structure is optimized to further improve the comprehensive performance of the system. Finally, the effectiveness of the proposed method is illustrated through an application example of the satellite attitude control system.

执行器故障和饱和情况下控制系统的可重构性评估和设计

本文探讨了针对存在执行器故障和饱和的系统的基于重新配置的容错控制问题。这项工作的基本思想是评估系统的可重构性，以指导重构方案和系统结构设计。首先，推导出一个可重构性标准，并利用该标准量化可重构性的程度。在此基础上，提出了一种被动/主动相结合的重新配置方法，以平衡重新配置方案的有效性和实施复杂性。此外，还优化了系统结构，进一步提高了系统的综合性能。最后，通过卫星姿态控制系统的应用实例说明了所提方法的有效性。

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.
