| 摘 要： | 针对求解动态EIV模型时未考虑状态方程中状态转移矩阵误差的问题，本文建立了一种能够同时顾及状态方程和观测方程中各量误差的动态EIV模型。推导了针对该动态EIV模型的总体卡尔曼滤波方法及其近似精度评定公式。对比分析了本文总体卡尔曼滤波方法与已有总体卡尔曼滤波方法及总体最小二乘方法的异同。算例结果表明，本文方法统计上要优于标准卡尔曼滤波方法和已有的总体卡尔曼滤波方法。

| Abstract: | For the case of the adjustment method of dynamic errors-in-variables(EIV)model ignoring the random errors in the state propagating matrix of system equations,this paper establishes a dynamic EIV model which considers the errors of each elements in both observation equations and system equations.A total Kalman filter method(TKF)and its approximated precision estimator are proposed based on this dynamic EIV model.The similarities and differences of the proposed method,the existing total Kalman filter methods and total least squares(TLS)methods are also analyzed.The results show that the proposed method is statistically superior to the standard Kalman filter method and the existing total Kalman filter methods. |
