Unmanned aerial vehicle attitude control system, flight control system and attitude control method

Abstract

The invention discloses an unmanned aerial vehicle attitude control system, a flight control system and an attitude control method. The unmanned aerial vehicle attitude control system is used for controlling pitching, yawing and rolling of an unmanned aerial vehicle, and comprises a main control system, a rudder system and a feedback system; the steering system is provided with at least three steering engines, the at least three steering engines are arranged at the tail of the unmanned aerial vehicle in a centralized mode, a rudder piece rotating shaft of each steering engine in the at least three steering engines is designed to be arranged in the mode of intersecting with the central axis of the tail of the unmanned aerial vehicle, and the included angles between any two adjacent rudder piece rotating shafts are equal. A rudder sheet driving control circuit of each steering engine in the rudder system is in signal connection with the main control system, and the rudder sheet of each steering engine in the rudder system is controlled by a corresponding attitude control instruction sent by the main control system to cooperatively rotate so as to enable the unmanned aerial vehicle torealize pitching, yawing and rolling motions required by attitude control; and the rudder system further comprises a steering engine positioning module.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle attitude control system, an unmanned aerial vehicle flight control system and an unmanned aerial vehicle attitude control method. Background technique [0002] The flight control system of UAV usually includes main control system, propulsion system, rudder system and feedback system. Among them, the propulsion system is used to provide thrust to keep the UAV flying; the rudder system is used to realize the steering of the UAV; the main control system is used to control the operation of the propulsion system and the rudder system; the feedback system is used to feed back to the main control system Control results for unmanned aerial vehicles. The UAV flight control system needs to match the type of UAV. At present, for UAVs that are long in shape and usually fly along their own length direction, the propulsion system and rudder system are usually set far apart in the length direction of UAVs, which i...

AI Technical Summary

Problems solved by technology

At present, for UAVs that are long in shape and usually fly along their own length direction, the propulsion system and rudder system are usually set far apart in the length direction of UAVs, which is easy for UAVs. The installation of other functional components creates obstacles, and it also brings inconvenience to the transportation and launch of UAVs
