Purpose

This paper aims to investigate the attitude regulation for spacecraft in the presence of time-varying inertia uncertainty and exogenous disturbances.

Design/methodology/approach

The high gain approaches are typically used in existing researches for theoretical advantages, bringing better performance but sensitive to parameter selection, making the controller conservative. A reset-control policy is presented to achieve the spacecraft attitude control with easy control parameter tuning.

Findings

The reset-control policy guarantees satisfying control performance despite using performance tuning function and saturation function besides reducing the conservativeness of the controller, thus reducing the effort in tuning control parameters.

Originality/value

Notably, the adaptive function owns a reset mechanism, which is reset to a preset condition when the controlled variable crosses zero. The mathematical analysis also shows the system trajectory can converge to a set centered at the origin.

重置和规定的航天器姿态调节性能方法

目的

本文旨在研究航天器在时变惯性不确定性和外生扰动下的姿态调节。

设计/方法/方法

现有研究中通常使用高增益方法以获得理论优势,带来更好的性能,但对参数选择敏感,使控制器保守。提出了一种复位控制策略,实现航天器姿态控制,控制参数调整简单。

发现

除了降低控制器的保守性外,复位控制策略在使用性能调整函数和饱和函数的情况下也保证了令人满意的控制性能,从而减少了调整控制参数的工作量。

原创性/价值

值得注意的是,自适应功能具有复位机制,当受控变量过零时,该机制被复位到预设条件。数学分析还表明系统轨迹可以收敛到以原点为中心的集合。
