摘要: 摘要: 针对卫星敏感器故障情况下的故障诊断与容错控制一体化设计问题,本文将敏感器有效性因子和控制器增益作为整体,利用区域极点配置方法设计综合输出反馈控制律,保证了良好的系统性能;再利用敏感器偏差的最优估计方法进行实时估计敏感器有效性因子,反解即可得到控制器增益,保证了控制的实时性和快速性;最后通过仿真验证了所提方法的有效性.

Abstract: Abstract:A method for integrated design of fault diagnosis and fault tolerant is proposed for a class of sensor fault. First, the sensor effectiveness factor and the controller gain are taken as a whole, so we can construct a combined output feedback controller via the theory of regional pole assignment. Then an optimal estimation method is given to estimate the sensor effectiveness factor in real time, which can be used to solve the controller gain. The well designed combined controller can ensure the system achieving a good performance while the realtime estimated sensor effectiveness factor can ensure the control is realtime and rapid. Finally, numerical simulations demonstrate the effectiveness of the proposed approach.    

Key words: Keywords:fault diagnosis, fault tolerant, spacecraft, effectiveness factor, regional pole assignment
