Vertical take-off and landing fixed ring automatic control unmanned aerial vehicle system

Abstract

The invention relates to a vertical take-off and landing fixed ring automatic control unmanned aerial vehicle system, comprising a PC control terminal based on a ground control system, and a fixed ring unmanned aerial vehicle, wherein the vertical take-off and landing fixed ring automatic control unmanned aerial vehicle system is characterized in that the fixed ring unmanned aerial vehicle comprises an unmanned aerial vehicle flight control unit, a camera shooting and collecting unit, a ground management unit and an energy unit. According to the vertical take-off and landing fixed ring automatic control unmanned aerial vehicle system provided by the invention, a controller combining a linear quadratic regulator with a proportional integral differential is adopted in the unmanned aerial vehicle flight control unit, an attitude sensor is adopted in the camera shooting and collecting unit, the flight attitude of the fixed ring unmanned aerial vehicle is stabilized by using the technologycombining the linear quadratic regulator with the proportional integral differential in the inner / outer loop control, in cooperation with the PC control terminal based on the ground control system, the problems of unstable inner loop angular speed control and worse flight safety are solved, the situation of flight deviation from a flight path is reduced, so that the flight efficiency is improved,and meanwhile, the use demands of the current vertical take-off and landing fixed ring automatic control unmanned aerial vehicle system are satisfied.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle systems, in particular to a vertical take-off and landing fixed-wing automatic control unmanned aerial vehicle system. Background technique [0002] Unmanned aircraft is referred to as "drone". With the rapid development of flight control technology, communication technology and electronic technology, the performance and types of unmanned aerial vehicles continue to increase, making them more and more popular in military and civilian applications. keep growing. At present, it is widely used in aerial photography, agriculture, plant protection, micro selfie, express delivery, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspection, disaster relief, film and television shooting, and romance creation. In addition to the use of drones themselves, developed countries are also actively expanding industry appl...

Problems solved by technology

However, since the engine cannot produce lift perpendicular to the axis of the fuselage, the fixed-wing UAV can only obtain lift through the relative motion between the fixed wing and the air, so as to overcome the gravity of the fixed-wing UAV, the size of the lift and the fixed There is a positive correlation between the relative velocity of the wing and the air, that is to say, the greater the relative velocity, the greater the lift obtained by the fixed-wing UAV

[0005] In the prior art, the vertical take-off and landing fixed-wing automatic control UAV system has the problems of unstable control of the inner ring angular velocity and poor flight safety, which makes the flight easy to deviate from the flight trajectory, resulting in relatively low flight efficiency and unable to meet the current vertical requirements. Requirements for the use of take-off and landing fixed-wing automatic control UAV system
