This paper is concerned with two problems: First, a formula is derived to estimate the error of system identification from the autoeorrelative function of stationary random disturbances and that of pseudo-random sequences. It can be used to select the type of pseudo-random sequences to be used for quick identification with a given error.

Secondly, when kalman filter has reached steady state its error covariance will have a very small stationary value, namely filter dropping off'. Thirdly, the traditional kalman filter cannot adjust its filter parameters with statistic characteristic of the noise. To overcome the deficiency of kalman filter, an SVD-based adaptive kalman filter is put forward in the paper. The filter restrains the filter divergence by matrix singular value decomposition. The eigenvalues and eigenvectors of the matrix are insensitive to tiny change of matrix element and acceptable error.

然而，传统的卡尔曼滤波器存在以下问题：问题一，因噪声统计特性估计不准确和计算机舍入误差引起的滤波发散现象；问题二，在卡尔曼滤波器达到稳态时，其误差方差阵将饱和使其对信号的突变变得不敏感，问题三，传统的卡尔曼滤波器对滤波参数无自适应能力，不能随着噪声统计特性的改变而调整自身的滤波参数。
