Embodiment Construction

[0006] The implementation of the UAV parameter adjustment method consists of a ground station, a flight control computer and a data transmission station. Through the operation interface of the ground station, the parameter commands that need to be adjusted are framed according to the set communication protocol, and then the parameter frame is sent to the UAV flight control computer using the data transmission radio.

[0007] After the flight control computer receives the parameter frame, it will deframe according to the set communication protocol to obtain the flight parameters for adjusting the controller. Subsequently, the relevant parameters of the drone can be adjusted and changed.

[0008] Take PID controller as an example, its control algorithm is:

[0009] δ u ( t ) = K p e ( t ) + K i ∫ 0 t e ( t ) dt + K d e · ( t )

[0010] Among them, e(t) is the error between the expected value of the dr...

Abstract

The invention discloses a method for adjusting the parameters of a unmanned aerial vehicle (UAV) controller, which is characterized by comprising a ground station, a flight control computer and a data transfer radio station, wherein the ground station is used for setting the parameters required to be adjusted, carrying out binding and layout on the set parameter instructions, and then sending the obtained parameter frames to the flight control computer of the UAV by the data transfer radio station; and the flight control computer is used for decoding frame on the parameter instructions, and then updating the parameters of the controller by using the obtained parameters, thereby achieving the purpose of adjusting the parameters of the UAV controller. By using the ground station, the flight control computer and the data transfer radio station, the method of the invention can achieve the purpose of adjusting the parameters of the controller conveniently, directly and safely in the flight process of the UAV without landing, dismantling the aerial vehicle or carrying out other hardware changes.

Description

Technical field [0001] The invention is a method for adjusting the parameters of the UAV controller, which can conveniently, quickly and safely adjust the controller parameters during the flight of the UAV. Mainly used in aerospace, unmanned aerial vehicles, robotics and other technical fields. Background technique [0002] The parameters of the UAV's controller are usually preset on the ground, and then adjusted according to the actual situation during the flight. However, the previous adjustment method was to connect the flight control computer to make changes after the drone landed. Since the adjustment of UAV controller parameters often requires several experiments to complete, this parameter adjustment method requires frequent take-off and landing of UAVs. Therefore, this method is not only very inefficient, but also frequent takeoffs and landings will significantly increase the probability of accidents, and even cause serious accidents such as plane crashes. The inventio...
