无人机动态测试中的故障注入研究

研究了一种在无人机动态测试中对飞行控制系统进行故障注入试验的专用系统——故障注入与分析系统。本课题首次将故障注入的方法和技术应用于无人机动态测试中,是无人机飞行控制系统研制、试验及性能评价的有效手段。与以往的故障注入研究不同的是,本文没有采用较常用的硬件实现方法,而是采用软件模拟的方法实现了硬件故障注入,大大降低了故障注入的实施难度,也减小了故障注入试验对目标系统的危险系数。

This paper studies a special system:fault injection and analysis system that was used in the UAV dynamic test to execute fault injection test.This paper applies the method and technique of fault injection to dynamic test for the first time.It is a valid means for UAV flight control system to research,experiment and evaluation.Differ from former fault injection researches,this paper does not adopt hardware method which was common used before but the method of software emulation and injection.The method reduce the implement difficulty of fault injection,also it weaken dangerous of target system brought by fault injection test.
