Example Embodiment

[0063] Example one

[0064] The first aspect of the present invention provides a control method of UAV, please refer to figure 1 , Is a flowchart of the control method of the drone in the embodiment of the present invention. The method includes:

[0065] S101: Obtain a first control instruction, where the first control instruction is an original control instruction used to control the drone to fly to a target state.

[0066] Specifically, the first control command is a single or integrated control command used to control the state of the UAV. The integrated control command can be a combined amount of speed and attitude, or a combined amount of overload, angular rate, and dynamic pressure. Control commands can control the actions of the drone.

[0067] S102: According to a preset ideal model, transform the first control instruction into a second control instruction that matches the expected response dynamics.

[0068] In the specific implementation process, because the control instruct...

[0102] Example two

[0103] Based on the same inventive concept as the drone control method in the aforementioned first aspect, the second embodiment of the present invention also provides a drone control device, such as figure 2 Shown, including:

[0104] The first obtaining module 201 is configured to obtain a first control instruction, the first control instruction being an original control instruction used to control the drone to fly to a target state;

[0105] The conversion module 202 is configured to convert the first control instruction into a second control instruction that matches the expected response dynamics according to a preset ideal model;

[0106] The feedback module 203 is configured to collect the flight state parameters of the UAV related to the second control instruction, and generate comprehensive feedback accordingly;

[0107] The second obtaining module 204 is configured to perform error control according to the second control instruction and the integrated feed...

Example Embodiment

[0121] Example three

[0122] Based on the same inventive concept as the drone control method in the first embodiment, the third embodiment of the present invention also provides a computer-readable storage medium, such as image 3 As shown, a computer program is stored thereon, and the following steps are implemented when the program is executed by the processor:

[0123] Obtaining a first control instruction, where the first control instruction is an original control instruction used to control the drone to fly to a target state;

[0124] According to a preset ideal model, transforming the first control instruction into a second control instruction that matches the expected response dynamics;

[0125] Collect the flight status parameters of the UAV related to the second control command, and generate comprehensive feedback accordingly;

[0126] Performing error control according to the second control instruction and the comprehensive feedback to obtain a third control instruction;

Abstract

An embodiment of the invention provides an unmanned aerial vehicle control method and device. The method includes the steps: acquiring a first control command which is an original control command forcontrolling an unmanned aerial vehicle to fly in a target state; transforming the first control command to a second control command conforming to an expected response dynamic; acquiring flight state parameters of the unmanned aerial vehicle related to the second control command and accordingly generating comprehensive feedback; controlling errors according to the second control command and the comprehensive feedback to obtain a third control command; controlling the unmanned aerial vehicle according to the third control command. Stability and robustness of the unmanned aerial vehicle control method are improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a control method and device for an unmanned aerial vehicle. Background technique [0002] At present, drones are widely used in map surveying, forest surveying, disaster monitoring, logistics express, high-altitude photography and other fields. [0003] The aircraft is essentially a complex nonlinear system. The traditional control method is to first linearize the mathematical model of the aircraft to obtain the linearized state equations of small disturbances in different modes, and then design corresponding control laws for different flight modes and carry out Adjust the parameters, and finally connect all the flight states to form the control law in the entire envelope. In the traditional control method, if the attitude of the aircraft changes drastically or is subject to large external interference, the aircraft cannot be effectively controlled, and it may even cause the...
