中文摘要:
      针对线性离散系统的执行器故障,提出了一种基于状态反馈的容错控制方法。该方法在应用自适应卡尔曼滤波进行系统状态和故障同步估计的基础上,通过故障信息和状态估计进行状态反馈,对闭环系统进行极点配置,从而修正执行器故障造成的系统误差,实现容错控制。最后,将该方法应用于飞行控制系统的执行器故障容错控制,仿真结果表明该方法不仅能够准确地进行故障估计,而且能够在故障情况下保证系统输出正常,具有一定的理论意义和实际工程应用价值。
英文摘要:
      A fault-tolerant control method based on state feedback was proposed for actuator faults of linear discrete system.Based on the synchronization estimations of system states and faults by an adaptive Kalman filter, state feedback was donevia the fault information and state estimation. The closed-loop system was pole-configured to correct the system errorcaused by the actuator faults and realize fault-tolerant control. Finally, the method was applied to fault-tolerant control forthe flight control system. The simulation results show that the proposed method can not only accurately estimate the faults,but also ensure the normal outputs of the system under fault conditions, which has certain theoretical significance and practi.cal engineering value.
