摘要: 介绍用Fliess 泛函展开式研究航天器姿态控制问题。首先讨论一步预测 及多步预测下的姿态跟踪。接着讨论当系统的解耦矩阵满秩时,在适当反馈下, 闭环系统的Fliess 泛函展开式具有有限项。由于航天器姿态动态方程具有非奇 异解耦矩阵,有限项Fliess 泛函展开式可以方便地应用于航天器姿态控制的在 线设计。

关键词: 姿态控制, Fliess 泛函展开式, 解耦矩阵, 输出跟踪

Abstract: The paper surveys the attitude tracking of aircrafts via Fliess functional expansion. First, one step and ¯nite step predictive controls are considered. Then we show that when the system decoupling matrix is of full row rank, using a proper state feedback, the closed-loop system has a Fliess functional expansion with only ¯nite terms. This approach is particularly suitable for the online design of attitude control of spacecraft.

Key words: attitude control, Fliess functional expansion, decoupling matrix, output tracking
