摘要：

针对存在参数不确定性和外加干扰的刚体航天器的姿态跟踪控制问题，提出一种基于二阶滑模的姿态跟踪控制方法。首先介绍高阶滑模控制基本原理，并建立基于修正罗德里格参数(modified Rodrigues parameter, MRP)描述的航天器数学模型，采用李雅普诺夫第二法推导二阶滑模姿态控制律。理论分析和仿真结果表明该方法能够有效消除系统抖振，并实现航天器姿态跟踪的精确定位，且系统具有全局稳定性和鲁棒性。

Abstract:

With the secondorder sliding mode control theory, a sliding mode attitude tracking maneuver control method is presented for a rigid spacecraft in presence of parameter variations and external disturbances. First the basic idea of the higherorder sliding mode control is introduced, then the spacecraft mathematical model is described by the modified Rodrigues parameter (MRP) and the secondorder sliding mode attitude control law is derived based on Lyapunov second method. Theoretical analysis and simulation results show that the method effectively eliminate system chattering and achieve spacecraft attitude tracking maneuver precision positioning and get global stability and robustness at the same time.
