无人飞行器舵机故障浅析

Fault Analysis of Steering Engine of UAV

无人飞行器的可靠性越来越受到重视。文中简要介绍了无人飞行器舵机故障的类型以及产生原因,分析了三种主要的排除故障途径,对比了其优缺点。最终以建模途径为例,推导了无人飞行器在飞行过程中受到的力及力矩,阐述了故障识别和诊断的流程,为进一步的仿真试验提供了新的方法和理论依据。

The reliability of UAV has been more and more appreciated.This article introduced the kinds and causes of steering engine fault of UAV briefly,then analyzed three main ways to shoot trouble and also compared their advantages and disadvantages.Finally,taking the way of web modeling for example,this article inferred the force and force moment of UAV in flying,and elaborated the procedure of distinguish and diagnosis fault.It is a new way and theoretical base for simulation testing.
