摘要
针对次优Sage自适应卡尔曼滤波器存在的不足,提出了两种改进措施:通过对滤波器发散的综合抑制,提高了滤波器的数值稳定性;设计了一种新颖的附加伴随滤波器的并行滤波结构,消除了针对结果偏移现象,提高了滤波精度。
This paper presents two innovations to solve the problems of the classical suboptimal Sage adaptive Kalman filter.The first innovation is to effectively improve the numerical stability by means of synthetically restraining the filter's disconvergency.The second is to use a parallel filter structure of adding a concomitant filter to eliminate system biases that the standard Sage adaptive filter always suffers,and the accuracy is also improved.
