Embodiment Construction

[0023] The present invention will be further described below in combination with specific embodiments.

[0024] figure 1 It is a schematic block diagram of the automatic homing control method of the present invention. Such as figure 1 As shown in , firstly, according to the location information of the forced landing site, the return route is determined. Using the information of the homing route and the best gliding speed, according to the side offset and airspeed information of the UAV, the airspeed control and the side offset control are respectively used for the elevator steering gear 2 and the aileron steering gear 6, so as to realize automatic homing. navigation control.

[0025] The following is an embodiment of the application of the present invention:

[0026] Step 1: Determine the return route;

[0027] According to the position information of the known forced landing field, two points are respectively selected as waypoints in the expected landing direction of the...

Abstract

The invention provides an automatic homing control method for unexpected stopping of the motor of an unmanned aerial vehicle, comprising the steps of homing course determination and automatic homing control. According the position information of a known emergency landing field, two points in the expected direction of the emergency landing field are selected as flight points, the longitudes and the latitudes of the two points are the longitudes and the latitudes of the flight points, and a flight course defined by the two flight points is a homing course; the automatic homing control is realized by the control of an elevator steering engine and an aileron steering engine; the elevator steering engine is controlled by air speed, the ileron steering engine is controlled by side setover; by the method, automatic homing control can be realized without the influence of objective conditions, including weather, weather in a short period of time and visual distance, when the motor stops unexpectedly, an airplane can fly towards the emergency landing field at an optimal glide speed, non-power landing chance is obtained, the unmanned aerial vehicle homes automatically, thus to reduce loss.

Description

technical field [0001] The invention relates to an automatic homing control method for unmanned aerial vehicles when the engine stops unexpectedly, and belongs to the field of automatic flight control of unmanned aerial vehicles. Background technique [0002] An aircraft engine is a complex system that integrates mechanical, electrical, and hydraulic technologies and uses thermodynamic principles to generate propulsion. The engine is the source of the aircraft's thrust. Once the engine stops unexpectedly, the aircraft will lose power immediately. The American Global Hawk UAV crashed due to engine failure during a flight test, causing heavy losses. [0003] A glider is a light aircraft without power. The forward power used to overcome aerodynamic resistance in the air is through the conversion of potential energy (or height), and it can land like a conventional aircraft. Usually, the ratio of the ground distance and the height loss of the gliding is called the glide ratio, ...
