摘要:

针对无人机跟踪未知平移和旋转运动目标的问题,设计了一种跟踪控制器。主要的挑战是将目标和UAV之间的相对位置和角度控制在期望值内,并且保证所生成的对UAV的控制输入是可行的(即,在其运动能力范围内)。此外,无人机被控制以确保目标始终保持在其机载摄像机的视野内。据我们所知,这是第一个应用多个无人机协同跟踪动态目标的工作,同时确保无人机保持连接,避免遮挡和碰撞。为了实现这些控制目标,基于上述跟踪控制器使用二次规划求解的设计的控制器可以生成最小侵入控制动作,以实现遮挡避免和碰撞避免。此外,控制障碍功能(CBF)的分布式设计,以减少无人机之间的通信量。仿真结果验证了所设计的基于CBF的多无人机系统控制器在跟踪目标时的有效性和性能。

英文摘要:

A tracking controller for unmanned aerial vehicles (UAVs) is developed to track moving targets undergoing unknown translational and rotational motions. The main challenges are to control both the relative positions and angles between the target and the UAVs to within desired values, and to guarantee that the generated control inputs to the UAVs are feasible (i.e., within their motion capabilities). Moreover, the UAVs are controlled to ensure that the target always remains within the fields of view of their onboard cameras. To the best of our knowledge, this is the first work to apply multiple UAVs to cooperatively track a dynamic target while ensuring that the UAVs remain connected and that both occlusion and collisions are avoided. To achieve these control objectives, a designed controller solved based on the aforementioned tracking controller using quadratic programming can generate minimally invasive control actions to achieve occlusion avoidance and collision avoidance. Furthermore, control barrier functions (CBFs) with a distributed design are developed in order to reduce the amount of inter-UAV communication. Simulations were performed to assess the efficacy and performance of the developed CBF-based controller for the multi-UAV system in tracking a target.
