无人机控制与导航系统故障分析及备件优化

摘要

针对某型无人机控制与导航系统的类型和特点，设计一种无人机控制与导航系统最优维修策略。利用故障树构建系统的故障模型，计算系统发生故障的概率，分析了各部件的重要度；建立航材备件数量的优化模型，得到了控制与导航系统航材备件的最优配置数量。该策略为控制与导航系统的维修提供了决策依据。%One optimal maintenance strategy for certain type unmanned aerial vehicle (UAV) is designed by analyzing the characteristics of the control and navigation system (CNS) of the UAV. The fault probability of the CNS is quantified and the importance of each components of the CNS is evaluated based on the fault tree model of the CNS. The optimum number of the aerial spare provision is assessed based on the optimization model of the CNS spare provision. The optimal strategy can support the maintenance decision-making.
