摘要

提出了一种非理想参数下涡扇航空发动机的定时切换控制方法。首先，考虑了模式识别的时间成本，导致控制器参数并不总是最适合航空发动机在每种工作模式下的参数。其次，设计了固定时间扰动观测器和固定时间反馈控制律，分别对总扰动进行估计和补偿，实现闭环跟踪；在控制器设计中减轻了对精确系统模型的依赖。第三，提出了在非理想参数下保证估计误差系统和闭环系统定时稳定性的新准则。最后，通过对某双轴涡扇航空发动机的应用，验证了所提方法的优越性。实验结果表明，该方法具有更快的响应速度和更强的鲁棒性，显著提高了暂态控制性能。

Fixed-time switching control of a turbofan aero-engine under non-ideal parameters

This paper proposes a fixed-time switching control method for a turbofan aero-engine under non-ideal parameters. First, the time cost of the mode identification is considered, which results in the controller parameters not always being best suited to the aero-engine in each operating mode. Second, the fixed-time disturbance observer and fixed-time feedback control law are newly designed to estimate and compensate the total disturbance, respectively, for achieving the closed-loop tracking. The reliance on an accurate system model is mitigated in the controller design. Third, novel criteria are proposed to ensure the fixed-time stability of the estimation error system and the closed-loop system, respectively, under non-ideal parameters. Finally, superiorities of the proposed method are verified through its applications to a double-spool turbofan aero-engine. Experimental results validate that the proposed method offers faster response speed and stronger robustness, which significantly improves the transient control performance.

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.
