无人机飞行控制系统软件故障注入方法研究

Research on software-based fault injection for flight control system of UAV

本文介绍了应用软件故障注入技术实现无人机飞行控制系统可靠性的评测方法。通过在无人机飞行控制计算机的外部数据总线上截获飞行参数,模拟无人机系统的硬件故障,构建故障模型并实现故障注入过程。实际应用表明该系统可以有效评估无人机飞行控制系统的故障检测、系统可靠性和容错能力。

In this article,the software-based fault injection technology is introduced to implement a reliability evaluation method for UAV flight control system.The system can block and acquit flight data form external data bus of UAV flight control computer to simulate hardware fault of UAV.Based on this flight data,fault model is built and fault injection process is accomplished as a result.The system has been successfully employed to verify the fault detection,fault tolerance and reliability of UAV flight control system.
