中文摘要
      本文研究了空间翻滚目标捕获任务中的相对姿轨耦合控制问题。为了提高系统在有界干扰、测量误差、控制受限、参数不确定等因素影响下的控制性能,设计了双滑模面姿轨耦合控制律,并证明了该控制律作用下闭环系统的稳定性。通过数学仿真与传统单滑模面控制律进行了对比分析,结果表明双滑模面控制律的能够显著减小稳态偏差和噪声。进一步,构建了地面微重力半物理试验系统,设计了轨道面内对翻滚目标逼近与跟踪的任务场景,通过半物理试验结果验证了双滑模面控制律在姿轨控全系统实时闭环、微重力动力学条件下的有效性。
英文摘要
      The relative attitude and orbit coupled control problem for capturing tumbling target in space is studied in this paper. To improve the control performance of the system impacted by bounded disturbance, measurement errors, limited control input, parameter uncertainty and so on, a dual sliding-mode surface control (DSMSC) method is designed, with the stability of the closed-loop system also proved. Numerical simulations are carried out to compare the performances of the single sliding-mode surface control (SSMSC) law and the DSMSC. The DSMSC is indicated to remarkably lower the steady statue control bias and noise. Furthermore, a set of ground micro-gravity semi-physical verification system is established, and a mission scenario is designed with the relative motion between the chaser and target constrained in the orbit plane of the target. Then, using this semi-physical verification system, the efficiency of the DSMSC is verified in the real-time closed-loop guidance navigation and control system under ground-simulated micro-gravity dynamics.
