| 摘 要： | 故障注入是一种用于容错计算机系统验证的有效技术,其应用效果直接取决于所采用的故障注入方法的正确性。文中采用硬件覆盖和故障模型的方法,模拟无人机系统的硬件故障,并着重讨论了在总线上注入故障的试验策略。然后用软件的方法构造了一个用于测评无人机飞行控制系统容错控制机制的故障注入工具UAVFI_01。在无人机动态测试过程中,故障注入试验结果表明了这种方案的正确性和可行性。

| Abstract: | Failure injection is an effective approach to validation of fault-tolerant computer systems.The effect of failure injection heavily depends upon the accuracy of a technique used.Hardware coverage and failure model are adopted to simulate hardware failures in unmanned aerial vehicles(UAVs) and a test strategy of bus-level failure injection is discussed in detail.A software-based failure injection tool,UAVFI_01,is developed to evaluate faulttolerant designs for UAV flight control systems.The results of an UAV dynamic failure injection test showed the validity and practicability of this scheme. |
