| 摘 要： | 针对观测数据异常导致滤波偏离的问题,提出了整体控制状态协方差阵自适应卡尔曼滤波方法,通过对某地铁隧道底板结构沉降监测数据进行处理,结果表明整体控制状态协方差阵自适应卡尔曼滤波方法不仅计算简单,而且能有效地控制观测数据异常对沉降变形监测系统参数估计的影响,提高变形监测数据估计的精度。

| Abstract: | In view of the filtering departure problem resulted from the observational outliers,an adaptive Kalman filtering method is proposed based on the robust variance matrix estimation.By the derivation and calculation for the deformation monitoring data of a metro,it is shown that the adaptive Kalman filtering method could not only predigest the calculation process,but also improve the precision of the estimation for deformation monitoring data. |
