摘要

提出了一种利用重力梯度和大气转矩对2U立方体卫星三轴姿态进行调节的控制算法。对航天器的惯性张量进行修正，使航天器保持重力梯度稳定构型。基于李雅普诺夫的控制律同时提高了利用大气转矩调节俯仰角的性能。

Spacecraft Attitude Regulation in Low Earth Orbit Using Natural Torques

This paper presents a control algorithm for three axis attitude regulation of a 2U CubeSat by means of gravity gradient and atmospheric torques. The inertia tensor of the spacecraft is modified to keep the spacecraft in a gravity gradient stable configuration. A Lyapunov-based control law acts simultaneously to improve the pitch angle regulation performance using atmospheric torque.
