摘要：

针对追踪航天器接近和跟踪非合作目标任务中的相对位姿控制问题，基于预设性能控制理论提出一种低复杂度预设性能控制方法(LCPPC)。该控制方法一方面无需对模型的具体参数（如追踪航天器与非合作目标的质量、惯量参数等）进行先验估计或在线辨识，另一方面又能预先设计系统的瞬态和稳态性能，保证相对位姿控制系统在存在外部干扰、不确定性和非合作目标不可测机动的条件下仍能满足预先设计的性能要求。仿真结果表明，该控制方法能够在未知系统参数的条件下，实现非合作目标交会任务的快速实时高精度控制。

Abstract:

A low-complexity prescribed performance control (LCPPC) method on basis of the prescribed performance control theory is proposed in this paper for a chasing spacecraft approaching and tracking a non-cooperative target spacecraft. Any information of the system parameters, including the mass and inertia matrix of the chasing and target spacecraft, is unnecessary. Moreover, the transient performance as well as the steady performance of the system can be prescribed and guaranteed despite the external disturbance, parameter uncertainties and unknown non-cooperative target’s maneuver. The simulation results show that the high precision real-time control is realized for approaching and tracking the non-cooperative target in a line-of-sight coordinate system.

Key words: Prescribed performance control, Non cooperative target, Model free, Low complexity, Robust control
