Embodiment 1

[0051] An embodiment of the invention provides a method for controlling the cruising of an aviation vehicle. Such as figure 2 As shown, the control method for the cruising of the aviation vehicle includes the following steps (S101-S104):

[0052] S101. Obtain the balanced skewness value of the throttle valve in the height-stable state of the altitude-fixed cruising stage of the aeronautical aircraft;

[0053] The aerial vehicle referred to in this embodiment may be an unmanned aerial vehicle or a human-piloted aircraft.

[0054] In the present embodiment, after the aviation vehicle enters into the fixed-altitude cruising segment, the aviation vehicle enters the fixed-altitude flight mode in a flight area with relatively good wind conditions (using figure 1 The high-altitude cruise mode can reach the fixed-altitude cruise), at this time, enter the closed-loop control of the altitude and the closed-loop control of the speed, wait for the flight altitude of the aircraft to be ...

Embodiment 2

[0070] This embodiment provides an aviation vehicle. The aviation vehicle can implement the method for controlling the cruising of the aviation vehicle provided in Embodiment 1. This embodiment only briefly describes the structure of the aircraft, and for other unfinished matters, please refer to the description in Embodiment 1.

[0071] Such as Figure 5 As shown, the aviation vehicle includes: acquisition module 10, setting module 20 and control module 30; in addition, the aviation vehicle also includes: throttle, pitch angle control loop and PID controller (not shown on the figure), wherein:

[0072] The obtaining module 10 is used to obtain the balanced deflection value of the throttle valve in the altitude stable state of the aviation vehicle in the fixed-altitude cruise stage;

[0073] Setting module 20 is used to fix the deflection value of the throttle to a balanced deflection value;

[0074] The obtaining module 10 is also used to obtain the actual true air speed; ...

Abstract

The present invention provides a method for controlling the cruising of an aviation vehicle and the aviation vehicle, wherein the method includes: obtaining the balanced skewness value of the throttle in the highly stable state of the altitude-fixed cruise stage of the aviation vehicle; fixing the skewness value of the throttle as Equalize the skewness value; obtain the current actual true airspeed of the aircraft; calculate the speed error between the actual true air speed and the given true air speed, and perform closed-loop control on the speed of the airborne aircraft through the pitch angle control loop according to the speed error. The present invention performs closed-loop control on the speed of the aircraft by fixing the deflection value of the throttle and through the pitch angle control circuit, and can completely solve the increase in fuel consumption caused by frequent changes of the throttle while ensuring that the flight height does not change greatly and does not stall. question.

Description

technical field [0001] The invention relates to the field of cruising of an aviation vehicle, in particular to a control method and the cruising of an aviation vehicle. Background technique [0002] At present, medium-high altitude and long-endurance UAVs usually control the flight height through a closed-loop control of the pitch angle and the true speed through a closed-loop control of the throttle to complete the vertical control during the air cruise stage. see figure 1 , the given flying height is the expected cruising height, and the height error is calculated between the given flying height and the actual flying height, and the height error value is input as an input parameter into a proportional-integral-differential (Proportion Integration Differentiation, PID) controller, and the PID controller The output value is input into the pitch angle control loop, and the pitch angle control loop outputs the elevator deflection command to perform closed-loop control on the ...
