摘　　要：研究不确定飞行控制系统执行器中断故障检测与分离问题,同时设计了状态反馈控制器和检测器,在保证闭环控制系统稳定的前提下,通过设计的检测器对系统状态进行重组以产生残差进而检测执行器的中断故障.此外,通过设计一组分离器,可以确定出执行器发生故障的位置.最后,通过研究一个飞行控制系统模型验证了所提出方法的有效性.This paper studies the fault detection and isolation problem for uncertain flight control systems with actuator outage faults, which has not been well investigated in the literature. A state feedback controller and a detection weighting matrix are designed simultaneously, through which the closed-loop system is stabilized for both fault-free and actuator outage cases, and the actuator outage faults can be detected through the residual signal generated by recombining system states with the detection weighting matrix. Additionally, a set of isolation weighting matrices are designed to identify the locations of the actuators that are of outage. A VTOL aircraft model is given to illustrate the effectiveness of the proposed methods.
