The present application relates to the field of unmanned aerial vehicle control, in particular to a rotor unmanned aerial vehicle control method based on lift feedback, the rotor unmanned aerial vehicle control method based on lift feedback includes designing unmanned aerial vehicle control framework with lift feedback power system and lift closed loop controller based on rotor lift model and motor electric governor model. First, remove the motor speed inverse solution module in the traditional power system in the unmanned aerial vehicle control framework, increase the lift feedback control module, use the sensor to measure the lift generated by the rotor, realize closed loop control;Second, the power system model of multi-rotor unmanned aerial vehicle is established, the motor throttle is taken as the input, and the rotor lift is taken as the output;Finally, based on this model, the input-output linearization force closed loop controller is designed to accurately control the lift output. The method solves the problems of low control accuracy and poor flight stability of the rotor unmanned aerial vehicle in the wind disturbance environment operation or maneuvering flight process. By applying this control method to the rotor unmanned aerial vehicle to ensure its high precision control and stable flight in the wind disturbance environment and maneuvering flight process.
