一种交叉双旋翼无人机桨叶损伤识别与安全返航方法

本发明属于无人机健康监测与飞行安全控制技术领域，具体涉及一种交叉双旋翼无人机桨叶损伤识别与安全返航方法，包括以下步骤：获取多源状态数据；对所述多源状态数据进行预处理；基于所述特征数据提取时域特征参数和频域特征参数；基于预设的加权评估函数，根据所述时域特征参数计算桨叶损伤风险指数；基于所述桨叶损伤风险指数及预设的多级阈值，判定桨叶损伤等级；响应于所述桨叶损伤等级，执行对应的飞行控制策略，所述飞行控制策略包括保持任务飞行、降级飞行控制或安全返航控制。本发明，能够解决现有技术中多源信号耦合干扰导致损伤识别维度单一、以及异常状态下缺乏分级控制与能耗优化返航策略的问题。
