Problems solved by technology

When the IMU fails and there is no other IMU backup, the flight controller will no longer be able to obtain accurate attitude feedback, resulting in abnormal attitude control, and the UAV cannot fly normally or even crashes.
[0005] For the above problems, no effective solution has been proposed

Abstract

The invention provides a flight control method and system for a triple-redundancy IMU, and relates to the technical field of aircraft control, wherein the method comprises the steps: obtaining working parameters, transmitted by the triple-redundancy IMU, of a to-be-detected aircraft, wherein the working parameters comprise at least one of the following parameters: a three-axis gyroscope parameter, a three-axis acceleration parameter and a temperature parameter, and the triple-redundancy IMU comprises three IMU devices; determining an intermediate value of the working parameters sent by the triple-redundancy IMU; and determining an abnormal IMU based on the intermediate value and the working parameters sent by the triple-redundancy IMU. Therefore, the technical problem of relatively low abnormal detection accuracy of the aircraft in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of aircraft control, in particular to a method and system for flight control of triple redundant IMUs. Background technique [0002] With the continuous maturity of small drone technology and the continuous expansion of market demand, the use of drones in power inspection, agricultural plant protection, aerial survey and exploration, aerial photography and other fields is becoming more and more common. [0003] The normal operation of the flight control of the UAV can ensure the stability of the flight and the smooth completion of the task. For small UAVs, the overall low cost requirements lead to the use of relatively simple flight controls, and most of the sensors do not have backups, and the tolerance for abnormalities in flight is relatively low. Especially the IMU sensor responsible for obtaining the attitude of the drone, once there is a problem during the flight, it is easy to cause a flight ...
