Solar unmanned aerial vehicle flight management and control method based on task priority

Abstract

The invention discloses a solar unmanned aerial vehicle flight management and control method based on task priority. The method comprises the following steps of: defining subsystems, different flight stages and different load types of a solar unmanned aerial vehicle as different tasks; dynamically adjusting the priorities of the tasks in real time according to task priorities; uniformly managing all the tasks by a flight management and control system, with the current task with the highest priority taken as the primary task, and other tasks being carried out around the task with the highest priority. The flight management and control strategy based on the task priorities is adopted, different priority schemes are executed in different flight tasks and flight stages, the system complexity can be reduced, the system reliability can be improved; and in addition, the optimal efficiency of each task can be improved, the optimal scheme of the solar unmanned aerial vehicle system can be optimized, and the flight safety can be improved,. The method has very high engineering application value.

Description

technical field [0001] The invention relates to the technical field of solar-powered drones, in particular to a flight management and control method for solar-powered drones based on task priority. Background technique [0002] Solar-powered UAVs fly at near-space altitudes and can fly across day and night. They have the characteristics of low flight speed, light weight, great flexibility, and great wind field influence. At present, the design of solar-powered UAV adopts the traditional UAV design idea. The aircraft system, power system, energy system, load system, flight control system, etc. are independently designed. Each system has its own controller and control strategy. The onboard software communicates. [0003] figure 1 It is a schematic diagram of traditional solar UAV flight management and control. Each subsystem and flight stage tasks are independent of each other, work in series, and independently manage and control the corresponding system. The protection stra...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when designing flight management and control strategies, the control and protection strategies of load, energy, power, and flight control equipment are considered, that is, the management and control strategies of solar drones are formed, which can easily lead to layer-by-layer protection of sub-systems , thereby limiting the performance output of the aircraft

In addition, different missions and different stages of flight are executed sequentially, which fails to maximize the performance of the aircraft and load performance
