The invention provides an unmanned aerial vehicle power system, an unmanned aerial vehicle control method, an unmanned aerial vehicle control device and an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The system comprises power suites arranged on rotor shafts, and high-voltage electronic speed controllers of the power suites are used for receiving control signals sent by a flight control system; the control signal is determined based on a target control rotating speed after the flight control system determines the target control rotating speed based on an accelerator signal of a preset proportion; controlling a high-voltage motor to rotate based on the control signal to drive a propeller to rotate; in the rotation process of the high-voltage motor, the operation parameters of the unmanned aerial vehicle meet the following conditions that a current accelerator signal is located in a first preset range; the current motor efficiency is greater than preset efficiency; the current rotating speed is within a second preset range; the sum of the pulling forces of the rotor shafts of the unmanned aerial vehicle is greater than the target weight of the unmanned aerial vehicle. In the rotation process of the high-voltage motor, it needs to be guaranteed that the operation parameters of the unmanned aerial vehicle meet the conditions, and therefore the efficiency of the unmanned aerial vehicle power system can be improved.
