非合作式自主交会对接的自适应鲁棒控制

Adaptive Robust Control for Approach of Autonomous Rendezvous and Docking with Non-cooperative Target

研究非合作式自主交会对接的近距离接近问题,以一个翻转卫星的平面追踪问题为例子,用交会对接过程中外界干扰的估计值构造能量函数,根据Lyapunov稳定判据提出一种自适应鲁棒控制率。最后进行的数字仿真验证了该控制率是可行的,并且满足非合作式自主交会对接的高精度和抗干扰的要求。

The proximity guidance of autonomous rendezvous and planar tumbling satellite chasing problem is presented as a case study docking with non-cooperative target is researched. A The system energy function is constructed by means of the estimation of the external disturbances in the stage of autonomous rendezvous and docking, According to Lyapunov stability criterion, an adaptive robust control law is presented. Finally, the numerical simulation results demonstrate that the adaptive robust control law is efficient and satisfies the requirements of precise and anti-jamming in the stage of autonomous rendezvous and docking with non-cooperative target.
