We integrate the two step filter with a time varying measurement noise statistical estimator to obtain an adaptive two step filter, which still performs well in the case where the statistical properties of the measurement noise are unknown apriori. 本文将这种滤波器与时变测量噪声统计估值器相结合,得到一种自适应两步滤波器,在测量噪声统计特性无法验前已知的情况下,此滤波器仍然性能良好。
Based on the transformation of the time varying parameter estimation to the state estimation for state equations, a recursive algorithm is derived according to the Kalman filter principle. The sufficient condition of asymptotical stability for the algorithm proposed is also given. 其原理是将时变参数的估计转化为对状态方程的状态估计,采用卡尔曼滤波推导出参数估计递推公式,并研究了其渐近稳定的充分条件。
