摘要

基于两台 6-DOF 工业机器人的三维空间非合作目标卫星在轨对接作业的地面微重力验证与测试,由于风险大、成本高,且受地球重力的影响,因此十分必要且意义重大。地面微重力验证系统的研制主要采用混合仿真方法,包括真实接触硬件测试实验和虚拟软件仿真。为了实现地面微重力环境的仿真,系统中需要对非合作目标卫星进行重力补偿算法。采用导纳控制方法实现软对接功能,保证对接任务的成功,主要模拟太空对接过程中的真实接触力和真实运动状态。地面验证实验结果表明,服务卫星能够在三维空间成功对接或捕获自由漂浮的非合作目标卫星。

Ground micro-gravity verification of free-floating non-cooperative satellite docking
Ground micro-gravity verification and test for the on-orbit docking operation of non-cooperative target satellites in 3-dimensional space based on two 6-DOF industrial robots is essential and significant owing to the high risk and cost and the influence of the earth gravity. The development of ground micro-gravity verification system mainly adopts the hybrid simulation method, which includes the real contact hardware test experiment and the virtual software simulation. To realize the emulation of ground micro-gravity environment, the gravity compensation algorithm of the non-cooperative target satellites is necessary in the system. The admittance control method is adopted to realize the soft docking function to ensure the success of the docking mission, which mainly simulates the real contact force and the real motion state during the docking process in space. The ground verification experiment results show that servicing satellite can successfully dock or capture the free-floating non-cooperative target satellites in 3-dimensional space.
