| Abstract: | The characteristics of the lift generating physics of lift- fan aircraft differ from conventional air- craft. The forces and moments of the aircraft are analyzed in detail, and the full variable mathematical model of vertical take- off UAV is established and the detailed longitudinal and lateral control strategies are given as well. Conventional control law method is adopted to design the attitude, longitudinal and lat- eral control loop of vertical takeoff period, and control simulation platform is established. Through the sim- ulation results, the motion characteristics of this type aircraft are analyzed, and the validity and feasibility of the control system are validated. |
