摘要
对自适应卡尔曼滤波建立的滤波模型在计算中对初始参数的要求进行了研究,并根据时间监测资料计算的结果,得出了自适应卡尔曼滤波具有对初始参数要求比较宽松、能根据计算时的观测数据自动调整参数的功能.利用该模型对某大跨径桥梁的实际监测资料进行分析,通过与统计分析的比较,验证其有效性.
A study is conducted on the preliminary parameters on the basis of adaptive Kalman filtering model in this paper. The calculation results of actual monitoring data show that the adaptive Kalman filtering's request for preliminary parameters is flexible and the parameters can be automatically adjusted.This dynamic model has been applied to the factual data analysis of a long-span bridge.The model proves effective when it is compared with statistic analysis.
