The invention relates to the field of rotor unmanned aerial vehicles, in particular to a rotor unmanned aerial vehicle power system based on lift force feedback, which replaces traditional motor rotating speed closed-loop control, performs closed-loop control by directly taking lift force generated by a rotor wing as a control object, and designs a force feedback controller. According to the power system, a force sensor is used for directly measuring the lift force, filtering processing is conducted on data output by the sensor, the data serve as feedback signals of force closed-loop control, and closed-loop control over the lift force of the power system is formed by building a force feedback controller. When the power system is applied to the rotor unmanned aerial vehicle, the maneuverability and robustness of the system can be effectively improved.
