摘要

AT PRESENT, a large number of engineers have assorted to fault-ntolerant control (FTC) to enhance the system reliability and tonguarantee the control performance (see, e.g., [1–4] and referencesntherein), and several investigations on the application of FTC tonspacecraft attitude maneuvers have also been considered. Forninstance, based on the dynamics inversion and time-delay control, anpassive fault-tolerant controller was developed in [5] to achievenattitude tracking of a rigid satellite. Cai et al. [6] proposed an indirectnadaptive fault scheme for spacecraft attitude tracking problem undernthruster faults. In [7], a control augmentation method, similar tonadaptive fault-tolerant control, was adopted for the flexible space-ncraft attitude tracking. However, all the preceding FTC results cannonly tolerate limited predetermined faults and have great conser-nvativeness due to its implementing a fixed controller only.
