The Research on the Reconfiguration Method of Flying-wing UAV Control System

The movement equation of aircraft is usually described in the Euler coordinate system,however,the motion equations are possible singular when aircraft flying is at high angle of attack.According to the traits of the flying-wing UAV,the model is established which is based on quaternion method six-DOF Mechanical.Due to the aerodynamic data interpolation of control surfaces,the NURBS interpolation method is used.After the interpolating data is fitted,the expressions about control surfaces data and rudder-face declination are gained.On the basis of the research,the UAV control surfaces fault is reconstructed by applying the SQP method.The results of simulation show that the methods proposed can reconstruct control surfaces fault and achieve good reconstruction effects.
