The design of control system and simulation analysis of key parameters at the launching process of the propeller UAV with double booster rockets are studied. The nonlinear mathematical model of the UAV launching process is set up, and the flight attitude control system consisting of control loops of the pitch angle, the roll angle and the yaw angle is designed. Then the simulation system of the UAV launching process control system is established to verify the effectiveness of the flight control system, and the influence of construction time of the propeller engine and the construction time of maximum thrust are investigated. Simulation results show that the flight control system can guarantee the stable climbing through effective control of the UAV＇s attitudes, and the clutching of the propeller engine and the maximizing of the throttle opening should be realized as early as possible on the premise of safe launching.
