Problems solved by technology

[0004] However, at present, the multi-rotor method is used in the take-off and landing process of the composite fixed-wing UAV, which relies on fixed position points. Complicated, the maximum flight speed in the horizontal direction can only be maintained at about 5m / s. At the same time, the maneuverability is limited, and it is difficult to take off and land on a moving base platform

Embodiment 1

[0040] like figure 1 , figure 2 and Figure 4 , a method for controlling the landing of a UAV based on a motion base, comprising the following steps:

[0041] S1, UAV approaching the motion base

[0042] UAV 2 flies to the rear of the motion base 1 after receiving the landing command, and maintains the preset accompanying flight altitude until the distance between the UAV 2 and the motion base 1 reaches the preset relative distance, and then turns on the rotor motor to switch to the composite flight mode;

[0043] S2, UAV guided flight escort

[0044] like Figure 5 , the rotor of the UAV 2 controls the UAV's attitude, heading, flight height, and the lateral relative position of the UAV 2 and the motion base 1; at the same time, the UAV 2 and the motion The longitudinal relative position of the base 1, and the relative speed between the UAV 2 and the motion base 1; the UAV 2 flies from the rear of the motion base 1 to just above the landing point of the motion base 1. Th...

Embodiment 2

[0051] Based on the UAV landing control method on the motion base, the method for the UAV to fly directly above the landing point on the motion base is as follows:

[0052] like Image 6 , the rotor of the UAV 2 controls the UAV's attitude, heading, flight height, and the lateral relative position of the UAV 2 and the motion base 1; at the same time, the UAV 2 and the motion The longitudinal relative position of the base 1, and the relative speed of the UAV 2 and the motion base 1; the rotor of the UAV 2 controls the UAV to roll and maneuver to a preset lateral relative distance from the motion base 1, and then passes The engine controls the UAV 2 to fly in the direction of the motion base 1, so that the UAV reaches the side of the landing point of the motion base 1; after the UAV reaches the side of the landing point of the motion base 1, the UAV is controlled by the engine. The longitudinal relative position and relative speed of the UAV 2 and the motion base 1 are within t...

Abstract

The invention belongs to an aircraft control method. The invention discloses a composite configuration fixed-wing unmanned aerial vehicle landing control method based on a motion base, a computer readable storage medium and control equipment. The objective of the invention is to solve the problem that in the prior art, a composite configuration fixed-wing unmanned aerial vehicle depends on a fixedposition point in a take-off and landing process so that it is difficult for the unmanned aerial vehicle to land on a moving base platform. Landing is divided into four steps of approaching, accompanying flight guiding, height reducing and landing completing, descending, postures and heading directions of the unmanned aerial vehicle are controlled through rotors, meanwhile, the transverse relative positions and speeds of the unmanned aerial vehicle and a moving base are controlled, and an engine controls the longitudinal relative positions and speeds of the unmanned aerial vehicle and the moving base. Corresponding hardware serves as a carrier of the computer readable storage medium and the control equipment, and the landing control method is achieved.

Description

technical field [0001] The invention belongs to an aviation vehicle control method, in particular to a motion base-based compound configuration fixed-wing unmanned aerial vehicle landing control method, a computer-readable storage medium and a control device. Background technique [0002] Conventional UAVs are generally divided into two types: fixed-wing and multi-rotor. Fixed-wing UAVs have the advantages of fast flight speed, long battery life and long range, but they need to use the runway for taxiing during take-off and landing, and cannot hover in the air; multi-rotor UAVs can take off and land vertically, There are no special requirements for the take-off and landing site, and it can also hover in the air, but the flight speed and endurance are difficult to compare with fixed-wing drones. [0003] The derived compound configuration fixed-wing UAV is to add a multi-rotor mechanism on the basis of the layout of the conventional fixed-wing UAV, so that the fixed-wing UAV...
