摘　　要：卫星通常工作在各种扰动环境中,包括参数不确定性和非参数不确定性。工程实践中碰到的另一个重要问题是控制输入受限。考虑存在参数不确定性和非参数不确定性,研究控制输入受限情况下卫星的姿态控制问题,设计了一种鲁棒自适应控制器,证明了姿态控制系统是全局一致最终有界稳定。仿真结果验证了该控制器的有效性。Satellites commonly operated in the presence of various disturbances, including parametric and non-parametric uncertainties. In addition, another important problem encountered in practice is that of control input saturation. In the presence of parametric and non-parametric uncertainties, this paper studied attitude control problems of satellite under control input saturation, designed a robust adaptive attitude controller, and proved that the attitude control system was global uniform ultimate bounded stable. Simulation results confirm the effectiveness of the controller.
