In order to control the position and attitude of unmanned aerial vehicle (UAV) better in different environments, this study\nproposed a hybrid control system with backstepping and PID method for eight-rotor UAV in different flight conditions and\ndesigned a switching method based on altitude and attitude angle of UAV. The switched process of hybrid controller while\nUAV taking off, landing, and disturbance under the gust is verified in MATLAB/Simulink. A set of appropriate controllers\nalways matches to the flight of UAV in different circumstances, which can speed up the system response and reduce the\nsteady-state error to improve stability. The simulation results show that the hybrid control system can suppress the drift\nefficiently under gusts, enhance the dynamic performance and stability of the system, and meet the position and attitude of\nflight control requirements.
