航天器姿态控制算法研究综述

Review of Attitude Control Algorithm for Spacecraft

航天器姿态控制在很长时间内一直是一个活跃的研究课题,航天器模型本身的非线性性质,加上不确定性参数和干扰,使姿态控制问题很具吸引力和挑战性。近年来,航天器姿态控制方法得到了快速发展,出现了许多系统性和鲁棒性优良的控制设计方法。文章对近年来的航天器姿态控制相关方法进行了分析、总结,分别对航天器姿态控制系统组成、姿态控制任务进行了详细介绍,对姿态控制算法中的最优控制方法、自适应控制方法、PD控制方法和H2/H∞及其混合控制方法进行了对比分析,最后,作出了总结与展望。

Spacecraft attitude control method has been an active research topic all the time. The theory of attitude control system depends not only on the nonlinear nature of the spacecraft model, but also on parameter uncertainty and disturbance, which makes it flail of attractive and challenging. The method of attitude control algorithm for spacecraft developed fast in recent years, meanwhile, the attitude control system of spacecraft has realized attitude control systemic and robustness with the emergence of many control design method. Some typical approaches referring to recent literatures are classified and summarized in this paper, thus, the system composition and tasks of spacecraft attitude control are presented and discussed in detail. At the same time, Optimal control method, Adaptive control method, PD control method and H2/Ha~ and hybrid control method of spacecraft attitude control system are recommended and contrastively analyzed. Finally, we make a conclusion for this paper and an overview is made to guide the future development in the field.
