摘要
为了实现导引头伺服稳定平台角度传感器、陀螺仪和电机驱动三大关键部件故障时的快速诊断和保护,设计了一套故障诊断和保护的方法.该方法结合关键部件的固有属性以及导引头稳定平台的工作特点,对其工作状态实时监测,一旦状态量持续或瞬间超过设定阈值,即可触发相应报警或者必要的保护措施.该方法可以很好地在前期调试中发现和定位故障,以及在导引头整机调试中出现故障时能够及时保护,防止故障扩大恶化.经试验验证,该故障诊断方法准确可靠,满足使用要求.
Abstract
In order to realize the rapid diagnosis and protection of the three key components of the seeker servo stabilized plat-form,namely,angle sensor,gyroscope and motor drive,in case of fault,a set of fault diagnosis and protection methods is designed.This method combines the inherent properties of key components and the working characteristics of the seeker stability platform to monitor its working state in real time.Once the state quantity continuously or instantaneously exceeds the set threshold,the corre-sponding alarm or necessary protective measures can be triggered.This method can well find and locate the fault in the early commis-sioning,and can timely protect the fault in the whole seeker commissioning to prevent the fault from expanding and worsening.The test results show that the fault diagnosis method is accurate and reliable,and meets the use requirements.
