摘    要:为解决由视线倾角、视线偏角过大造成的飞行器对接存在误差的问题,实现飞行器交会轨迹的精准对接,提出基于雷达测距的飞行器交会对接误差补偿控制技术。建立空间参考坐标系,根据轨道根数计算结果,推导动力学状态方程,实现对飞行器交会对接过程中的动力学作用分析。按照雷达测距原理,计算飞行器的理论飞行时长及雷达装置作用距离,再联合相关参数指标,确定精度极限的取值范围,实现基于雷达测距的对接误差控制。在三坐标测量机结构模型中,定义飞行位姿拟合条件,再根据位姿误差求解结果,实现对误差参数的补偿修正处理,完成基于雷达测距的飞行器交会对接误差补偿控制方法的设计。对比实验结果表明,应用所提方法可以同时将视线倾角、视线偏角的取值控制在0°-45.0°的数值范围之内,能够较好解决飞行器错误对接的问题,符合精准对接飞行器交会轨迹的实际应用需求。

Abstract:To solve the problem of errors in aircraft docking caused by excessive line of sight inclination and line of sight deviation, and to achieve precise docking of aircraft rendezvous trajectories, a radar ranging based aircraft rendezvous and docking error compensation control technology is proposed. Establish a spatial reference coordinate system, derive the dynamic state equation based on the calculation results of orbital elements, and analyze the dynamic effects of spacecraft rendezvous and docking process. According to the principle of radar ranging, calculate the theoretical flight duration of the aircraft and the operating distance of the radar device, and then combine relevant parameter indicators to determine the range of accuracy limits, achieving docking error control based on radar ranging. In the structural model of a coordinate measuring machine, the flight pose fitting conditions are defined, and based on the pose error solution results, compensation and correction of error parameters are achieved. The design of a radar ranging based aircraft rendezvous and docking error compensation control method is completed. The comparative experimental results show that the proposed method can simultaneously control the values of line of sight inclination and line of sight deviation within the numerical range of 0 ° -45.0 °, which can effectively solve the problem of incorrect docking of aircraft and meet the practical application requirements of precise docking of aircraft rendezvous trajectories.
Keywords:radar ranging   Aerocraft   Rendezvous and docking   Error compensation control   Dynamic equation of state   Accuracy limit value   Line of sight inclination   Line of sight deviation
