Title:
ATTITUDE COMPUTATION METHOD FOR UNMANNED AERIAL VEHICLE, FLIGHT CONTROLLER, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/191981
Kind Code:
A1
Abstract:
An attitude computation method for an unmanned aerial vehicle, flight controller, and unmanned aerial vehicle. The method comprises: acquiring a pulling force generated by a propeller (31) driven by a rotating motor (32), and a rotational torque of the propeller (31) on a motor base (33); and determining, according to the pulling force generated by the propeller (31) and the rotational torque of the propeller (31) on the motor base (33), an attitude of an unmanned aerial vehicle (60). When an IMU has a failure, a flight controller (70) determines, according to the pulling force generated by the propeller (31) driven by the rotating motor (32) and the rotational torque of the propeller (31) on the motor base (33), an attitude of the unmanned aerial vehicle (60), and performs flight control on the unmanned aerial vehicle (60) accordingly, thus preventing a crash caused by an IMU failure.
