全驱动多旋翼平台将平移力与姿态解耦,使位置与姿态可独立控制,性能瓶颈从姿态能力转向执行器动态和控制有效性。本文在固定倾角全驱动六旋翼上对比基于模型的非线性动态逆控制器(几何NDI)与基于传感器的增量动态逆控制器(INDI),两者外环结构相同且均以500 Hz运行,性能差异主要源于逆控策略。实验涵盖五类工况:额定条件下的姿态阶跃跟踪、旋翼推力系数50%失配下的跟踪、外部侧向负载下的悬停抗扰、风扰下的航点跟踪、控制频率降低及传感器退化。结果表明,INDI在参数失配、风扰和传感器退化下优势明显,且在控制频率下降时保持更低位置误差;但频率降低时,几何NDI姿态跟踪表现更优。据作者所知,这是首个对具有解耦动力学的全姿态跟踪INDI控制器的实验验证。研究揭示了测量依赖与模型依赖逆控在鲁棒性与快速部署间的权衡。

原文摘要 · Abstract (English)

Fully actuated multirotor platforms decouple translational force generation from vehicle attitude, enabling independent control of position and orientation and shifting performance limitations from attitude authority to actuator dynamics and control effectiveness. This paper compares a model-based nonlinear dynamic inversion controller (geometric NDI) with a sensor-based incremental dynamic inversion controller (INDI) on a fixed-tilt fully actuated hexarotor. Both controllers share an identical outer-loop structure and are both executed at 500 Hz; therefore, performance differences can be attributed primarily to the inversion strategy. Controller performance is evaluated in five experiments covering attitude step tracking under nominal conditions and under a 50% mismatch in the rotor force coefficient, hover disturbance rejection under an external lateral load, waypoint tracking in the presence of wind gust disturbances, reduced control frequency, and injected sensor degradation. The results show that INDI offers clear advantages under parameter mismatch, gust disturbances, and sensor degradation, and maintains lower position errors across the controller-frequency sweep. However, its advantages are not universal: geometric NDI yields better attitude tracking at reduced control frequencies. To the authors' best knowledge, this work presents the first experimental validation of a full pose tracking INDI controller with decoupled translational and rotational dynamics. These findings highlight the trade-off between measurement-based and model-based inversion for robust control and rapid deployment of fully actuated UAVs.
