摘要
提出了一种新的次优Sage自适应卡尔曼滤波算法 ,该算法针对经典次优Sage滤波器经常存在的结果偏移现象 ,设计了一种附加伴随滤波器的并行滤波结构 ,消除了结果偏移 ,提高了滤波精度。
A novel method of sub optimal Sage adaptive Kalman filter is presented in this paper. A parallel filter structure of adding a concomitant filter is creatively designed to eliminate system biases that the standard Sage adaptive filter always suffers, and the accuracy is improved.
