Design and Implementation of Automatic Landing Control System for UAV Based on GPS

UAV's development history and UAV variety of launch and recovery are introduced in this paper, study UAV two automatic landing system and the advantages and disadvantages of the two compared and according to the existing conditions determined a suitable landing system scheme is adopted. In the determined on the basis of the program established UAV taxiing nonlinear model and landing model, respectively for automatic takeoff and landing control system design. The elevator control and nose wheel steering control are designed respectively for UAV Ground taxiing longitudinal and lateral control law using glide beam guiding system and auto leveling control system and lateral beam guiding system, combining the control law are designed UAV longitudinal automatic landing system control laws and lateral automatic landing control law and in the design of the control system and several common wind disturbance, adopted the surname simulation to verify the robustness of the control system. The design of UAV automatic take-off and landing control system program, basically meet the requirements, I believe the work of this paper will provide a useful reference for the future development of the UAV automatic take-off and landing technology.
