| 摘 要： | 针对具有多冗余执行机构的航天器姿态控制系统，给出了处理冗余的控制分配方案，该方案考虑了幅值和速度约束条件并实现了二次最优．仿真验证了分配环节的有效性，并比较了不同求解算法下的动态分配效果．针对执行机构可能出现的故障，提出了结合故障诊断与隔离系统的执行环节控制重构方法，实现了机构故障下的容错控制，通过卫星姿态跟踪控制仿真，验证了分配和重构环节与控制回路的相容性．

| Abstract: | Focusing on a spacecraft attitude control system with redundant wheels,a control allocation method is given in dealing with redundancy. In goal of quadratic optimal control,the allocation algorithm takes amplitude and velocity constraints into consideration. Effectiveness of dynamic control allocation algorithms is validated through simulation results,and comparison between different allocation algorithms is given. For possible failures of actuators,a control reconfiguration method is proposed on the assump... |
