AI Technical Summary

Technical Problem

In existing technologies, hydrogen-powered drones cannot accurately diagnose the type of failure in the event of a fuel cell malfunction. The path planning is disconnected from flight capability constraints, resulting in the return path failing to meet the dynamic constraints after the failure, which may lead to a crash.

Method used

A fault diagnosis and path replanning-based approach is adopted. By obtaining UAV status information through hierarchical fault diagnosis, a return path that meets dynamic capability constraints is generated. This includes fault mode recognition and dynamic capability constraint embedding path planning to ensure that the return path conforms to the actual flight capabilities of the UAV.

Benefits of technology

It enabled the safe return of the drone in the event of a fuel cell failure, improving the success rate of autonomous return and mission preservation capabilities in complex environments.

Abstract

本发明涉及无人机返航控制技术领域,且公开了基于故障诊断与路径重规划的氢能无人机返航控制方法,包括以下步骤:获取无人机的状态信息,基于状态信息执行分层故障诊断,对状态信息进行特征提取,获得初级故障特征,将初级故障特征输入至预训练的故障诊断模型。该基于故障诊断与路径重规划的氢能无人机返航控制方法通过分层故障诊断对故障模式及严重等级进行精准识别,据此生成包含飞行速度、爬升角、滚转角等关键参数在内的动态能力约束,并将该约束作为刚性条件嵌入路径重规划过程,确保所生成的返航路径中每一航段均不超出故障后无人机的实际飞行能力边界,从根本上解决了传统方法中路径规划与飞行能力相割裂的问题。
