中文摘要：

针对过驱动卫星中期望控制力矩到执行机构输出力矩的控制分配问题，考虑执行机构的最大输出力矩约束，研究了一种基于分布估计算法的动态控制容错分配策略，根据卫星当前任务与故障信息在线选择合适的执行机构。最后，对本文研究的动态容错控制分配策略进行了数学仿真实验，仿真结果验证了该策略的有效性。

英文摘要：

In order to solve the control allocation problem that distribute the desired control movement to in- dividual actuator for over - actuated satellite with constrained actuator output movement, a dynamic fault tolerant control allocation scheme based on estimation of distribution algorithm is studied to choose appropri- ate on-line actuator depending on the current task and the fault information of the satellite. Finally, the performance of the proposed scheme is demonstrated via numerical simulation for over-actuated satellite.
