摘要/Abstract

摘要： 飞行器操纵面的常见故障问题主要分为卡死和损伤两类,依据舵机的电机力矩与舵面上铰链力矩的关系,提出了一种新的利用舵机输入电压来诊断舵面常见的两种故障的方法,并可以进一步诊断出舵机的损伤程度。使用力矩电机模拟负载铰链力矩,并应用dSPACE系统和舵机搭建的半实物平台对上述方法进行了半实物仿真。仿真结果表明此种方法能在0.2~2 s内实现卡死和损伤故障的诊断,并可以进一步诊断舵面损伤严重程度。具有较好的实用价值。

Abstract: The aircraft control surface defaults of rudders were mainly divided into jam fault and damage fault. On the basis of the relationship between motor toque and hinge moment, a new method of using the motor voltage was proposed to detect the control surface'faults of rudder. And the method could detect the damage degree of the faults. Torque motor was used to play the role of hinge moment. And the new method was simulated by Semi-Physical system which is consisted of dSPACE system, PC and simulated rudder actuator. The results show that, the damage faults and jam faults can be detected in 0.5s between 1.5s. And also it can detect the damage degree. According to the above, this method has good practical value.

Key words: diagnosis of actuator fault, jam fault, damage fault, dSPACE
