卫星姿态控制的一种鲁棒控制方法

针对含有不确定性的Delta算子离散系统,研究了其鲁棒控制问题。鲁棒控制律的存在条件及设计由线性矩阵不等式描述,便于求解。将所得结果应用于卫星姿态控制系统的设计,以解决对模型进行线性化处理时产生的误差。针对所得控制律进行了仿真研究,结果证明了方法的有效性。

A Robust Control Method of Satellite Attitude Control

Robust control for Delta operator discrete systems with uncertainties is considered. The conditions of the existence of the robust controllers are given by a set of linear matrix inequalities, which facilitate the solutions of the robust controllers. The proposed method is applied to satellite attitude controller design to cope with the errors arising while linearization procedure. Numerical simulations are conducted, and the results justify the feasibility of the proposed method.
