神经网络在光传系统故障诊断中的应用研究

光传系统是针对传统电传操纵系统的不足提出的一种新型的飞控系统;飞控系统的高可靠性是飞行安全的重要保证,当飞机出现故障或者遇到意外损伤时,飞控系统能够快速地对故障进行诊断和隔离,对于保证飞机飞行任务的继续执行或者安全返航具有重要意义。文章针对三余度光传系统的常见故障,提出了一种基于概率神经网络（PNN）的故障诊断方法;并且建立了三余度光传系统仿真模型和常见故障的产生模块,应用概率神经网络进行系统的故障诊断;最后通过仿真诊断实例,证明了方法的有效性。

Study on Fault Diagnosis for Fly-By-Light Control System Based on Neural Network

The fly-by-light system is proposed for the shortage of the traditional fly-by-wire control system.The high reliability of the flight control system is important to ensure flight safety.When the aircraft has faults or accident injures,it is great important that the control system can quickly diagnose and isolate the fault to ensure the continued implementation of flight mission or the safe return.The paper aimed at the common fault for fly-by-light triplex redundancy control system,the approach of fault dia...
