| 摘 要： | 运用灰色系统理论，建立了动力调谐陀螺漂移和温度之间的数学模型，以补偿热漂移，提高动力调谐陀螺的使用精度。将状态估计与不良数据辨识理论作为数据预处理技术应用于灰色系统建模，以观测数据为依据进行状态估计，避免了常规建模中观测数据与实际数据同等对待的弊端。对数据作检测与辨识，使剔除不良数据后的状态估计结果更为精确，以提高灰色系统建模精度。

| Abstract: | Grey system theory was applied in constructing a model between temperature and drift of a dynamically tuned gyroscope in order to compensate the thermal drift and improve the accuracy of the gyroscope. The methods of state estimation, bad data detection and identification were applied in grey system modeling to get some more reasonable results comparing to the conventional grey system modeling methods. The proposed methods can be used as data preparation techniques to detect bad data. The modeling accuracy of grey systems is greatly improved by such methods. |
