摘要

在航空发动机控制中，快速响应能力对瞬态性能意义重大，尤其是当飞机在紧急情况下工作时。为了提高航空发动机的响应速度，本简报提出了一种采用开关系统方法的定时控制。首先，将航空发动机建模为开关系统，以更好地反映其在各种运行任务下的多模式特性。然后，提出了固定时间控制器，该控制器具有计算量小、易于实现等优点。为闭环系统在受限开关情况下的定时稳定性分析提出了新的标准。此外，还通过具体计算得出了收敛时间的上限。最后，通过实验结果验证了所提方法的优越性。

Fixed-Time Controller Design for Aero-Engines: A Switched System Approach

In the aero-engine control, fast response capability is significant in transient performance, especially when aircraft work in emergency scenarios. To improve the response speed of aero-engines, this brief proposes a type of fixed-time control using the switched system approach. First, aero-engines are modeled as switched systems to better reflect the multimode characteristics under various operating tasks. Then, the fixed-time controller is proposed, which has advantages of small computation and easy implementation. Novel criteria are proposed for fixed-time stability analysis of the closed-loop system under restricted switchings. Furthermore, specific calculations are provided to derive the upper bound for the convergence time. Finally, superiorities of the proposed method are validated through experimental results.

期刊介绍： The IEEE Transactions on Control Systems Technology publishes high quality technical papers on technological advances in control engineering. The word technology is from the Greek technologia. The modern meaning is a scientific method to achieve a practical purpose. Control Systems Technology includes all aspects of control engineering needed to implement practical control systems, from analysis and design, through simulation and hardware. A primary purpose of the IEEE Transactions on Control Systems Technology is to have an archival publication which will bridge the gap between theory and practice. Papers are published in the IEEE Transactions on Control System Technology which disclose significant new knowledge, exploratory developments, or practical applications in all aspects of technology needed to implement control systems, from analysis and design through simulation, and hardware.
