Abstract

The invention discloses an UAV(unmanned aerial vehicle) stability augmentation control method and device. A control module obtains a current disturbance moment of an UAV platform, determines precession angle velocity of a gyro device needing for suppressing disturbance according to the current disturbance moment and generates a driving instruction for driving the gyro device to generate a corresponding control moment, and sends the driving instruction to a servo-driven module; and the servo-driven module receives the driving instruction, drives the gyro device to deflect to provide the corresponding control moment so as to suppress the interference of the current transient disturbance on UAV attitudes. The control method and device can increase additional mechanical torque control quantityunder the condition of not changing an original aerodynamic moment control structure, and quickly provide the control moment which is far greater than that capable of being provided by the aerodynamic torque of an UAV body, thereby solving the problem of easy instability of the UAV when the UAV is subjected to the impact load, and greatly improving disturbance resistance and impact resistance capability of the UAV. Besides, the invention also provides the UAV having the technical advantages above.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and device for stabilizing an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] UAVs have the characteristics of wide range of uses, low cost, good maneuverability, and a wide range of use scenarios. They are widely used in aerial photography, plant protection, forest fire prevention, power inspection, public security anti-terrorism and other fields. In order to make UAVs have better environmental adaptability and passability in complex environments, UAVs are often required to be miniaturized and lightened as much as possible. However, the miniaturization of existing UAVs will inevitably lead to a decrease in the aerodynamic force of the body , Load capacity decline, anti-interference ability decline, and wind resistance performance are significantly reduced. Even without considering its miniaturization, existing dron...
