摘      要：This paper considers a fault-tolerant control and vibration suppression problem of flexible *** attitude dynamics is modeled by an interconnected system,in which the rigid part and the flexible part are coupled with each *** a model allows us to use the interconnected system approach to analyze the flexible *** distributed and decentralized observer-based fault-tolerant control schemes are developed,under which the closed-loop stability of flexible spacecraft can be ensured by using the cycle-small-gain *** with the traditional method,this paper considers the faults occurred not only in the rigid parts,but also in the flexible *** addition,the application of the interconnected system approach simplifies the system model of flexible spacecraft,thereby the difficulty of theoretical analysis and engineering practice of fault-tolerant control of flexible spacecraft are greatly *** results show the effectiveness of the proposed methods and the comparison of different fault-tolerant control approach.
