Abstract

The invention discloses a flight control method of a multi-rotor craft including a plurality of rotor assemblies. Each rotor assembly includes a motor and a rotor driven to rotate by the motor. The control method includes judging whether the rotor assembly meets power absence or not; if power absence occurs, the rotation direction of a motor of at least one rotor assembly except the rotor assembly meeting the power absence is changed according to the lateral tilting direction of the multi-rotor craft. The invention also discloses a flight control device, a control system of the multi-rotor craft and the multi-rotor craft.

Description

technical field [0001] The present application relates to the field of multi-rotor aircraft control, in particular to a multi-rotor aircraft and its control method, control device and flight control system. Background technique [0002] At present, multi-rotor aircraft are widely used in various fields. Multi-rotor aircraft can be mounted with professional aerial photography platforms and high-definition camera equipment. Operations, natural disaster detection, urban planning and construction high-altitude image reference, and various advertising high-altitude photography and other fields have broad market demand. [0003] Each rotor of the existing multi-rotor aircraft has a motor drive to provide power. When the motor of the multi-rotor aircraft fails or the rotor shoots or breaks, the aircraft loses its power source, which will cause the aircraft to roll over. Contents of the invention [0004] In order to at least partially solve the above problems, the present applic...
