摘要 为满足灵敏小卫星大角度姿态快速机动与机动后快速高精度稳定的需求,针对具有推力器与飞轮等异构执行机构的冗余配置方案,提出了一种在轨动态选择执行机构实施机动任务的控制分配策略.基于优化方法的控制分配算法将期望控制量在冗余混合执行机构间进行动态分配,根据卫星当前状态适时改变优化目标函数中各控制指令的权重,最后通过标准化的求解过程来完成对执行机构的动态选择.最后,针对Microsim仿真平台的执行机构配置所进行的数学仿真结果表明,该策略能够完成小卫星大角度姿态快速机动与高精度稳定的控制分配任务,并满足特定时期选择特定执行机构执行任务,以及限制最大机动角速度等约束条件. To meet the demand of quick maneuver at large angle and high precision stability during the process of maneuver for an agile small satellite,a control allocation strategy is proposed in this paper to control the maneuvering process with configuration of redundant thrusters and reaction wheels.The control allocation algorithm distributes the control requirement among mixed redundant actuators dynamically and changes the weights of control parameters presented in the optimized objective function to choose suitable actuators actuated.The normalized linear programming model is used to obtain the solution.The results of simulation on Microsim platform which is equipped with redundant thrusters and reaction wheels demonstrate the effectiveness of the proposed strategy.
