Data-Driven Autonomous Actuator Fault Diagnosis and Fault-Tolerant Control for Spacecraft Control System
摘要
Abstract
In this paper,a data-driven autonomous actuator fault diagnosis and fault-tolerant con-trol method for spacecraft control systems is proposed.The proposed method can invoke the ap-propriate 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 diag-nosis 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 va-lidity and feasibility of the theoretical results are verified by a simulation example.关键词
