Abstract

The invention discloses a control method of a multi-rotor unmanned aerial vehicle, the multi-rotor unmanned aerial vehicle (100), a control device (200) and a nonvolatile computer readable storage medium (300). The control method of the multi-rotor unmanned aerial vehicle comprises the following steps: (01) acquiring the power state of each rotor of the unmanned aerial vehicle; and (02) when the power failure of any rotor wing of the unmanned aerial vehicle is determined based on the power state, controlling the unmanned aerial vehicle to enter a balance mode, wherein in the balance mode, the unmanned aerial vehicle rotates at an angular speed larger than a first threshold value, and the displacement of the unmanned aerial vehicle in the horizontal direction is smaller than a preset displacement amount.

Description

technical field [0001] The present application relates to the technical field of aircraft safety, in particular to a control method of a multi-rotor UAV, a multi-rotor UAV, a control device and a non-volatile computer-readable storage medium. Background technique [0002] Due to its simple structure, low cost, and easy control, multi-rotor UAVs have been widely used in many fields such as education and scientific research, aerial photography, military reconnaissance, and police safety. [0003] Multi-rotor UAVs include multiple motors and propellers. The motors drive the propellers to rotate to generate lift and reverse torque. Through a series of control algorithms and distribution strategies, the lift and control torque required for UAV flight are generated to control unmanned vehicles. machine position and attitude. However, when the power of a certain rotor fails completely, that is, when a certain motor stalls or the blade shoots, the drone will crash immediately, caus...
