| 摘 要： | 针对考虑传感器故障的柔性航天器姿态系统，提出了一种主动容错控制方法.首先，通过对测量输出进行滤波，将传感器故障转化为执行器故障形式；接着，设计一个基于未知输入观测器的自适应故障估计观测器，对未知故障进行辨识，同时，采用了一个故障检测观测器，对故障的发生进行检测；然后，利用故障估计信号对系统输出进行调节，结合自适应积分滑模和线性矩阵不等式技术设计输出反馈容错控制器；最后，对所设计的主动容错控制方法进行仿真，验证了所提方法的有效性.

| Abstract: | In this paper, an active fault tolerant attitude control approach is provided for a flexible spacecraft to accommodate the unknown sensor faults.Firstly, a model-based fault detection and estimation technique is developed into the process behavior by using a virtual filter and an adaptive observer.Secondly, a reconfigurable attitude controller design is developed by combining both adaptive integral sliding mode control and linear matrix inequality technique.Finally, the effectiveness of the proposed fault tolerant scheme has been verified by simulation result on a flexible spacecraft attitude control system with a time varying sensor fault. |
