为了加强小型无人直升机故障分析的安全性和可靠性,采用了故障检测隔离技术(FDI),通过对小型无人直升机实际飞行数据的试验验证和分析,验证了无人直升机舵机检测与诊断系统的实用性,并被广泛应用于评估自由故障植入前提下的飞行器任何位姿信息的差异,这个差异可由一个观测器来显示.
為瞭加彊小型無人直升機故障分析的安全性和可靠性,採用瞭故障檢測隔離技術(FDI),通過對小型無人直升機實際飛行數據的試驗驗證和分析,驗證瞭無人直升機舵機檢測與診斷繫統的實用性,併被廣汎應用于評估自由故障植入前提下的飛行器任何位姿信息的差異,這箇差異可由一箇觀測器來顯示.

Fault detection and isolation(FDI)technology is used to enhance the security and the reliability of fault analysis of small?size unmanned helicopters. The experimental verfication and analysis of real flight data of small?size helicopters prove that actuator detection and diagnosis system of unmanned helicopters has practicability and is widely applied to difference evaluatation of position and pose of aircrafts under the premise of implanting of free faults. And the difference can be displayed by a monitor.
