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

Abstract

The invention discloses an attitude control system of an unmanned aerial vehicle, a flight control system and an attitude control method. The unmanned aerial vehicle attitude control system is used to control the pitch, yaw and roll of the unmanned aerial vehicle, including: a main control system, a rudder system, and a feedback system; the rudder system has at least three steering gears in total, and the at least three The steering gear is centrally arranged at the tail of the unmanned aerial vehicle, and the rotation shafts of the steering blades of each of the at least three steering gears are designed to intersect with the central axis of the tail of the unmanned aircraft and any two adjacent steering blades rotate The included angles between the axes are equal, and the rudder drive control circuits of each steering gear in the rudder system are respectively connected to the main control system signal, and the rudder blades of each steering gear in the rudder system are controlled by the corresponding attitude issued by the main control system The commands control the coordinated rotation so that the unmanned aerial vehicle realizes the pitch, yaw and roll motions required for attitude control; the rudder system also includes a steering gear 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
