摘　　要：提出一种数据驱动的航天器控制系统执行器故障自主诊断和容错控制方法。所提出的方法能够根据故障诊断结果,调用合适的状态反馈容错控制器,实现系统的状态反馈镇定。首先,表征不同故障下的系统运行模式。其次,利用黎曼几何知识和系统不同运行模式下的数据特征矩阵,设计执行器故障诊断方案。再次,设计一组数据驱动的状态反馈容错控制器,实现系统在不同运行模式下的状态反馈镇定。然后,将状态反馈容错控制器与诊断方案结合,实现航天器控制系统的执行器故障自主诊断与容错控制。最后,通过仿真实例验证理论结果的有效性和可行性。In this paper,a data-driven autonomous actuator fault diagnosis and fault-tolerant control method for spacecraft control systems is proposed.The proposed method can invoke the appropriate state feedback fault-tolerant controller according to the fault diagnosis results to achieve state feedback stabilization of the system.First,the system operating modes under different faults are described.Second,based on the knowledge of Riemannian geometry,the actuator fault diagnosis scheme is designed by using the data feature matrix of different system operating modes.Third,a set of data-driven state feedback fault-tolerant controllers are designed to achieve state feedback stabilization of the system under different operating modes.Then,the state feedback fault tolerant controllers are combined with the diagnosis scheme to realize the autonomous actuator fault diagnosis and fault-tolerant control of the spacecraft control system.Finally,the validity and feasibility of the theoretical results are verified by a simulation example.
