Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] see figure 1 , figure 1 It is a flow chart of the flight control method of the multi-rotor aircraft in the first embodiment of the present invention. In this embodiment, the multi-rotor aircraft includes a plurality of rotor mechanisms, and the plurality of rotor mechanisms provide power for the multi-rotor aircraft, and the flight control method includes the following steps:

[0022] Step S11: Detect whether the output power of the plurality of rotor mechanisms is abnormal.

[0023] In step S11, for example, the multi-rotor aircraft can be a quad-rotor aircraft, a hexa-rotor aircraft or an octo-rotor aircraft, etc., each rotor mechanism includes a motor and a rotor driven by the motor, and whether the output power of multiple rotor mechanisms is abnormal can be detected by Detect the output of the motor to judge.

[0024] Step S12: When it...

Abstract

The invention discloses a flight control method for a multiple-rotor-wing aircraft. The multiple-rotor-wing aircraft comprises multiple rotor wing mechanisms; the multiple rotor wing mechanisms provide power for the multiple-rotor-wing aircraft. The flight control method comprises the following steps: detecting whether the output power of the multiple rotor wing mechanisms is abnormal or not; if detecting that the output power of partial rotor wing mechanisms is abnormal, adjusting the output power of other rotor wing mechanisms, so as to enable the multiple-rotor-wing aircraft to keep balanced. The invention further discloses a flight control system for the multiple-rotor-wing aircraft. Through the above mode, additional power can be saved to stabilize the attitude, therefore, that the multiple-rotor-wing aircraft lands in a loss minimization manner is ensured, and the damage of the parts of the aircraft and damage to vehicles and people on the ground, which are caused by direct crash of the aircraft are avoided.

Description

technical field [0001] The invention relates to the technical field of aircraft control, in particular to a flight control method and system for a multi-rotor aircraft. Background technique [0002] At present, multi-rotor aircraft are widely used in various fields. Multi-rotor unmanned aerial vehicles can be mounted with professional commercial aerial photography platforms and high-definition camera equipment, and can be widely used in ecological environment protection, mineral resource exploration, marine environment monitoring, and land use. Fields such as investigation, water resources development, crop growth monitoring, agricultural operations, natural disaster monitoring, urban planning and municipal construction high-altitude image reference, forest disease and pest protection monitoring, and various advertising high-altitude photography have broad market demand. [0003] Each rotor of the existing multi-rotor aircraft is driven by a motor to provide power. When the ...
