摘要
分析了天线传动系统影响电机电流特性的因素。提出了天线正常跟踪卫星的电流特性标准,电流在6 A以下属于正常范围。利用电机电流分析法,对测控天线传动系统的周期性故障、阻尼增大故障以及系统级故障进行定位判断,提出了产生故障的因素。同时,分析了上述三类故障对测控天线的跟踪性能的影响。结果表明,电机电流分析法可以对天线传动系统的故障进行预判断,有效避免系统级故障的发生,确保天线运行在良好的跟踪状态。
The factors of antenna drive system affecting motor current characteristics are analysed. The standards of motor current characteristics, for antenna normally tracking the satellite, are proposed. The motor current be- low 6A is in the normal range. Motor current analysis （MCA） is applied to the fault diagnosis of antenna drive system for periodic failure, damped increasing failure and fatal failure. At the same time, the impact of the three types of fault of drive system on tracking performance is analyzed. The results show that MCA can be used to pre - judge the fault of antenna drive system, which can effectively avoid fatal failure, and ensure the antenna to track satellite in good condition.
