针对飞行中典型的操纵面损伤故障，以故障检测滤波器为基础，开发了一种建立在离散模型上的快速、稳定的故障检测及诊断算法，可以在几个采样周期内同时精确检测出多个操纵面的损伤程度，故障检测滤波器的稳定性、收敛性也得到证明，具有较好的实用性。几种组合故障下的仿真研究证实了上述结论。 Aiming at the typical control plane damage in flight, based on the fault detection filter, a fast and stable fault detection and diagnosis algorithm based on the fault model was developed, which can detect more and more accurately in several sampling periods The degree of damage of a control surface, fault detection filter stability, convergence has also been proven, with good practicality. The simulation studies under several combination failures confirm the above conclusion.
