| 中文摘要 |
| 针对一般航天器动力学姿态控制问题, 提出了一种二阶线性自抗扰控制方法. 该控制方法对航天器系统中存在的不确定性及外界干扰具有很强的抑制能力, 且具有比较简单的结构, 解决了传统控制方法过多依赖航天器精确模型的问题. 在此基础上对航天器进行指令跟踪、抗扰性及性能鲁棒性实验, 并与带趋近律的滑模控制进行比较.仿真结果表明, 在参数不确定和外界干扰影响下, 自抗扰控制方法能获得良好的动态性能、抗扰性和较强的性能鲁棒性. |
| 英文摘要 |
| Considering the dynamics of spacecraft in attitude maneuver, we propose an active disturbance rejection control (ADRC) which has strong rejection ability for perturbations and disturbances. This control technique gets rid of a precise model required in traditional control methods. We have conducted the experiments of command-tracking,disturbance rejection and robustness investigation, and compared the results with those obtained from a sliding mode control (SMC) with a reaching law. The comparison shows that ADRC exhibits better dynamic performance, higher ability in disturbance rejection and stronger robustness against the parameter uncertainty and external disturbance. |
