Abstract

Active vibration control (AVC) in Unmanned Air Vehicles (UAV) enhances flight stability, enables lighter and more efficient designs, and improves fuel efficiency and payload capacity. However, AVC systems require careful design, and this study demonstrates how they can be efficiently tuned on a fixed-wing, composite aircraft drone using a purely experimental approach, leveraging the newly developed Experiment-in-the-Loop (EITL) method. The EITL is a real-time optimizer, capable of autonomously running hundreds or thousands of experimental tests on a target structure. In each test, the EITL iteratively refines the control parameters, progressively improving their performance. The EITL offers the advantage of being fast, tuning the controllers within hours, and not relying on numerical models. In this paper, 9 AVC systems are tuned, including four Positive Position Feedback (PPFs) controllers and five higher-order controllers. Experimental results show that these controllers reduce vibrations on the composite aircraft drone by an average of 55 % over 7 resonant modes in the frequency range from 0 to 250 Hz. In addition, results show how AVC systems can be practically implemented using lightweight hardware. The developed scaled-down AVC system weighs 183.8 g and occupies 273.5 cm³, making it a promising solution for onboard UAV applications.

基于环上实验系统的固定翼复合飞机无人机主动振动控制器的调谐与小型化

无人机中的主动振动控制（AVC）增强了飞行稳定性，实现了更轻、更高效的设计，并提高了燃油效率和有效载荷能力。然而，AVC系统需要精心设计，本研究展示了如何使用纯实验方法，利用新开发的循环实验（EITL）方法，在固定翼复合飞机无人机上有效地调整AVC系统。EITL是一个实时优化器，能够在目标结构上自主运行数百或数千个实验测试。在每个测试中，EITL迭代地细化控制参数，逐步提高它们的性能。EITL的优点是速度快，可以在数小时内调整控制器，并且不依赖于数值模型。本文对9个AVC系统进行了整定，包括4个正位置反馈控制器和5个高阶控制器。实验结果表明，在0 ~ 250hz的频率范围内，这些控制器在7种共振模式上平均减少了55%的振动。此外，结果还显示了如何使用轻量级硬件实际实现AVC系统。开发的按比例缩小的AVC系统重183.8 g，占地273.5 cm3，使其成为机载无人机应用的有前途的解决方案。
