    摘要:

    无人机在航拍过程中,由于气流、风速等外部因素的影响,其姿态容易发生变化,从而影响航拍画面的稳定性。为了提升无人机的航拍质量,实现对目标区域的稳定拍摄,提出基于状态实时反馈的无人机航拍姿态鲁棒控制方法。考虑航拍任务和航拍环境,通过无人机航拍路线规划和姿态解算,设定无人机航拍姿态控制目标。利用状态实时反馈技术测定无人机姿态初始值,便于更快地响应无人机姿态的变化。从偏航角和俯仰角两个方面设置控制约束条件,实现无人机在航拍过程中的全方位姿态控制。选择无人机中的机翼和动力系统作为航拍姿态鲁棒控制对象,综合考虑无人机飞行环境和控制量计算结果,动态生成无人机航拍姿态鲁棒控制指令,实现无人机航拍姿态的鲁棒控制。通过实验得出结论:状态实时反馈偏差低于0.2°,满足无人机航拍姿态鲁棒控制运行要求,姿态角执行偏差系数降低0.685°,同时姿态角执行偏差系数明显降低。

    Abstract:

    During aerial photography, drones are prone to changes in posture due to external factors such as airflow and wind speed, which can affect the stability of the aerial footage. In order to improve the quality of drone aerial photography and achieve stable shooting of the target area, a robust attitude control method for drone aerial photography based on real-time state feedback is proposed. Consider aerial photography tasks and environments, and set unmanned aerial vehicle (UAV) attitude control objectives through UAV aerial photography route planning and attitude calculation. The use of real-time state feedback technology to determine the initial value of drone attitude facilitates faster response to changes in drone attitude. Set control constraints from both yaw and pitch angles to achieve all-round attitude control of the drone during aerial photography. Selecting the wings and power system of the drone as the object of robust attitude control for aerial photography, taking into account the flight environment and control calculation results of the drone, dynamically generating robust control commands for the drone"s aerial photography attitude, and achieving robust control of the drone"s aerial photography attitude. The conclusion drawn from the experiment is that the real-time feedback deviation of the state is less than 0.2 °, which meets the requirements of robust attitude control operation for drone aerial photography. The attitude angle execution deviation coefficient is reduced by 0.685 °, and the attitude angle execution deviation coefficient is significantly reduced.
