| 摘 要： | 本文提出了一种利用传递函数求解多变量线性定常系统稳态卡尔曼滤波器次优增益阵的新方法,由传递函数直接导出次优增益阵,从而避免了求解高阶非线性矩阵黎卡提方程。在求解时,通过尽可能地设置非零自由参数,并使所有参数为同一数量级,可较容易地解出次优增益阵K~(?),然后进行灵敏度分析或仿真,选出理想的常增益阵K~(?)。

| Abstract: | In this paper, a new method for solving the suboptimal gain matrix of the stable Kaiman filter of the multi-input-multi-output, constant linear systems is presented. It avoids solving the high order nonlinear Riccati matrix equations and achieves the result directly from the transfer function. In the process of getting the results, and putting the nonzero parameters free, the suboptimal gain matrix K* can be solved. |
