导弹伺服机构中电液伺服系统故障诊断方法研究

摘要

为实现导弹伺服机构中电液伺服系统这类复杂系统的故障诊断,依据系统特点通过故障分析建立故障库,从系统中抽取局部采样点,再与故障库对比来进行故障诊断.通过实例验证了这一方法的实用性和有效性,为类似复杂液压系统故障诊断的实现提供了参考.%To realize the fault diagnosis for electro-hydraulic servo system of missile servo mechanism, the fault-base was built by fault analysis according to system character. The sampling points of local system were gotten from complicated system and fault diagno sis was made by contrast of fault-base. An example to validate the utilities and practicalities was given, which provided reference for complex hydraulic systems fault diagnosis.
