| 摘 要： | 针对飞机舵面损伤故障检测和诊断的气动模型和飞行状态限制，提出了在线故障模式预测方法，并使用某机的故障及正常风洞数据建立了舵面损伤非线性气动模型。最后，仿真验证了该方案的气动模型独立性、飞行状态及操纵的适应性。结果表明，该方法可提高自修复飞控系统中舵面损伤故障检测算法的适用性和工程应用能力。

| Abstract: | On-line fault mode predication method was designed to enable the control surface damage detection and diagnosis to be used under different aerodynamic model, different maneuvering and steering condition so that the self-repair flight control system can be more flexible and more practicable. Nonlinear aerodynamic model for control surface damage was built according wind tunnel data and simulation was done to testify the model and maneuvering independence of this algorithm. |
