摘　　要：自主控制是航天器控制系统设计追求的一个重要目标.针对在有限配置资源下如何最大程度提高控制系统中执行机构的控制能力这一问题,提出了一种基于故障及欠驱动情况的反作用轮配置优化方法,该方法综合考虑了反作用轮在正常、故障及欠驱动阶段的控制能力.首先,根据反作用轮配置优化的目的对简洁的4轮装反作用轮进行配置优化问题的描述;其次,根据反作用轮在整个寿命阶段可能发生的故障情况,对4轮装反作用轮在故障阶段的控制能力进行具体的分析;然后,根据其在每个故障阶段的控制能力建立反作用轮配置优化模型,从而求解出反作用轮在整个寿命阶段下的最优配置;最后,利用该方法对一工程实例进行配置解析,并针对可能发生故障的3种工作阶段进行仿真验证.仿真结果表明,本文所提出的配置优化方法能够有效实现航天器的自主运行,证明该方法可行和有效,具有一定的工程应用价值.Autonomous control is an important goal pursued in the design of spacecraft control systems.Aiming at maximizing the control ability of the actuator in the control system under the limited configuration resource,a reaction wheel configuration optimization method is proposed,which considers the fault and under-actuated condition,and comprehensively considers the reaction wheel control capability in the fault and under actuated stage.Firstly,the description of the optimization problem of the simple 4-wheeled reaction wheel configuration is carried out according to the purpose of the reaction wheel configuration.Secondly,according to the possible failure situation of the reaction wheel in the whole life stage,the control ability of the 4-wheeled reaction wheel in the fault stage is analyzed.Thirdly,according to the control ability of the 4-wheeled reaction wheel in each fault stage,the reaction wheel configuration optimization model is established to find the optimal configuration under the whole life stage.Finally,the configuration of a project instance is analyzed via this method.The simulations are carried out for the three working stages that may occur.The results show that the proposed method can effectively realize the autonomous operation of the spacecraft,which proves that the proposed method is feasible and effective,and thus has certain engineering value.
