Modeling and direction-controlling for flying-wing UAV in ground motion

The UAV has the unique dynamical characteristics in ground motion different from that of flight in the air. Establishing the mathematics model in this stage is important to realizing the safe take off and landing of UAV. As regards a flying-wing UAV, on which the strength pressed was analyzed, a nonlinear modal on ground motion was established. And the lateral control law of UAV ground sliding was designed using rear wheel dissymmetry braking and resistance rudder control in line. With the simulation environment of Matlab/Simulink, a simulation system was designed. The simulated result shows that the model can be used.
