Abstract

The invention discloses a thrust steering device of an unmanned aerial vehicle and a control method thereof. The device consists of two steering gears, an X-directional steering gear and a Y-directional steering gear, a universal ball joint, a steering gear pedestal, a joint bearing and an engine base. The control method comprises a control method of a longitudinal attitude of an unmanned aerial vehicle based on the thrust steering device of the unmanned aerial vehicle, a control method of a horizontal attitude of the unmanned aerial vehicle based on the thrust steering device of the unmannedaerial vehicle, a control method of a longitudinal trajectory of the unmanned aerial vehicle based on the thrust steering device of the unmanned aerial vehicle and a control method of a horizontal trajectory of the unmanned aerial vehicle based on the thrust steering device of the unmanned aerial vehicle. Due to the thrust steering control technology based on height differences, cross-track errors and other trajectory information, the invention can realize the better control of the unmanned aerial vehicle, and improve the accuracy of trajectory control.

Description

technical field [0001] The invention relates to the field of UAV flight direction change control, in particular to a UAV thrust direction change device and a control method thereof. Background technique [0002] An unmanned aircraft is a powered, controllable, unmanned aerial vehicle that can carry a variety of mission equipment, perform multiple tasks, and can be reused, referred to as a drone. It is the inevitable result of the automation, integration, intelligence and unmanned development of modern aircraft. With the needs of applications and the development of aviation technology, unmanned aerial vehicles have become the strategic technology highlands that all developed countries must compete for in recent years. [0003] Thrust vectoring technology refers to the technology that the thrust component generated by the engine thrust through the deflection of the nozzle or tail jet replaces the control surface of the original aircraft or enhances the control function of the ...
