The flight control technique of a small tilt rotor Unmanned Aerial Vehicle( UAV) during its mode transition period is investigated. Firstly,the model of the tilt rotor UAV and its mode transition strategy are introduced. Then,the longitudinal model of tilt rotor UAV is established and trimmed at its equilibrium points in order to obtain the transition path throughout the mode transition period. In addition,height and airspeed control structure are given and the mode transition control law is designed. Finally,all-digital simulation is done of the tilt rotor UAV mode transition period. The results indicate that the tracking of height and air speed of the tilt rotor UAV are effective. As a result,the tilt rotor UAV has a stable and safe mode transition period.
