摘要

亲爱的编辑，这封信通过设计一种鲁棒模型预测控制（RMPC）方案来解决受外部干扰和能见度限制的四旋翼飞行器的跟踪问题。根据基于图像的视觉伺服（IBVS）方法，我们构建了一个虚拟相机来表达跟踪目标的图像矩。此外，在 RMPC 优化问题中，我们设计了时变可见度约束，以迎合无人机的姿态，从而使跟踪目标始终保持在航空相机的视场（FoV）内。此外，RMPC 算法被证明是递归可行的，并且闭环系统是稳定的。最后，数值实验验证了所提方法的有效性。

RMPC-Based Visual Servoing for Trajectory Tracking of Quadrotor UAVs with Visibility Constraints

Dear Editor, This letter deals with the tracking problem of quadrotors subject to external disturbances and visibility constraints by designing a robust model predictive control (RMPC) scheme. According to the image-based visual servoing (IBVS) method, a virtual camera is constructed to express image moments of the tracking target. Furthermore, we design time-varying visibility constraints to cater to UAV attitudes in the RMPC optimization problem so that the tracking target always stays within the field of view (FoV) of the aerial camera. Moreover, the RMPC algorithm is proved to be recursively feasible, and the closed-loop system is stable. Finally, numerical experiments verify the efficacy of the proposed method.
