摘　　要：针对无人飞行器舵面损伤故障引起的气动参数大范围变化,采用线性自抗扰控制技术,将舵面损伤故障引起的被控对象特性变化,当作参数的有界摄动进行实时估计和补偿,将被控对象整定成不受特性变化影响的标称对象,实现对舵面损伤故障的被动容错控制。提出了一种基于频域分析的参数比值整定原则,保证控制器在舵面正常和故障两种情况下的鲁棒性和动态性能,仿真结果校验了该方法的有效性。According to the large range of parameters caused by the control surface damage of UAV（ Unmanned Aerial Vehicles）,the linear active disturbance rejection control is adopted. The active disturbance rejection control treats the change of controlled object characteristics as bounded disturbance,and it can estimate this disturbance real-timely then compensate it via control signal,so as to translate the controlled object into nominal object which won ＇t be affected by the change of characteristics,and then make the UAV with control surface damage satisfies the robustness requirement of passive fault-tolerant.A parameter tuning method is proposed based on frequency analysis,which can make the controller owns enough robustness requirement and dynamic performance under the circumstance of normal and damage.The simulation results are provided to demonstrate the effectiveness of the proposed method.
