| 中文摘要 |
| 针对混合估计自适应滤波器的工程应用问题，首先证明了交互式多模型算法（IMM）在一定条件下，其模型输入交互方差可与状态解耦，并给出了两模型下的IMM的模型输入交互方差之间部分解耦及完全解耦的条件，从而将常增益滤波器一IMM相结合，提出两模型常增益IMM自适应滤波器算法.仿真表明在精度与IMM相当的情况下，计算量减少了约50%，并消除了单模型常增益滤波器的有偏性 |
| 英文摘要 |
| In this paper, we firstly prove in interacting multiple modeis algorithm (IMM) model-conditional estimational variances can be decoupled with model-conditonal state estimation under certain conditions, and then supply the conditions to partly-decoupling and absolutely-decoupling among model-conditional estimational variances. Therefore IMM based on
α-β ＆ α-β-γ filters is proposed. The Momte Carlo simulations show that this algorithm not only remains almost as accurate as IMM, but also save about half of the computation. |
