摘要
建立了小卫星相对轨道和姿态的误差动力学模型,根据作业任务和姿态指向要求确定了小卫星相对轨道和姿态的期望运动;采用相对轨道和姿态联合控制策略,并考虑小卫星作业过程中质量和转动惯量的不确定性,设计了自适应全状态反馈控制律;数值仿真结果表明该控制律具有较强的自适应性。
Positional and attitude error dynamics model of small satellite relative to a target satellite was derived, then the desired relative orbit and desired attitude of small satellite were designed. Orbital and attitude cooperative control strategy was used and the parametric uncertainty of small satellite was considered. An adaptive full-state feedback controller was designed. Numerical simulation shows the controller is adaptive well.
