摘　　要：某型导引系统中,用行程继电器实现对位标器框架的锁定,采用FPGA实现对行程继电器的控制。在系统上电时,出现行程继电器非正常动作。通过分析试验现象和故障机理,提出了故障解决方法并通过了试验验证。该方法在继电器控制、电机控制方面,对上电瞬间异常工作故障分析方面具有较高的参考意义。In a certain guiding system, the target seeker platform is locked by a stroke relay and the FPGA im- plements the control of the relay. On the system when power, the stroke relay appears abnormal actions. Through analyzing the test phenomenon and the fault mechanism, A solution is proposed and verified by experiment. The method of fault analysis when power on has a high reference significance on relay control and motor control.
