Description

technical field

[0001] The invention relates to the field of aircraft, in particular to a control method for a dual redundant system of an unmanned aerial vehicle. Background technique

[0002] UAVs are easily affected by various factors during the flight movement, such as weather factors, wind factors, electromagnetic factors, flight environment factors and human factors, which make the UAV prone to failure. The failure of the UAV will delay the work, and cause the crash of the UAV, resulting in certain property losses.

[0003] At present, there is a patent titled "A Dual-redundant Aviation Power Supply and Its Power Supply Mode", with the application number 201110258227.2, which discloses a dual-redundancy aviation power supply and its power supply mode, which is realized on the power supply module of the drone. The dual-redundant design ensures that as long as two batteries do not fail at the same time, the power supply module can provide stable and continuous power to ...
