| description | The embodiment of the invention provides a satellite power supply system abnormity detection method. The method comprises the following steps: acquiring satellite power supply system data; according to the satellite power supply system data, establishing a power supply system model during normal operation of the satellite by utilizing LSTM (Long Short Term Memory); predicting the future state of the satellite power supply system according to the power supply system model; and updating satellite power supply system data, and correcting the power supply system model. Under the condition that the system is abnormal, the system state can still be effectively predicted based on historical data. Detection results show that the method has a low false alarm rate and a high detection rate, which are 9.18% and 98.37% respectively.
本发明实施例提供了一种卫星电源系统异常的检测方法，包括以下步骤：获取卫星电源系统数据；根据所述卫星电源系统数据，利用LSTM建立卫星正常运行时的电源系统模型；根据所述电源系统模型对卫星电源系统的未来状态进行预测；更新卫星电源系统数据，对所述电源系统模型进行修正。在系统出现异常的情况下，仍然能基于历史数据对系统状态做出有效预测。检测结果表明，该方法具有较低的虚警率和较高的检出率，分 |
