| 摘 要： | 传统的SSM算法是一种一维非线性系统参数估计算法。通过构造特殊状态空间矩阵对二位非线性系统进行参数估计,并在此基础上提出一种二维频率配对的方法。仿真实验证明该算法具有噪声抑制强、计算量低、分辨率高、估计方差小等优点。

| Abstract: | The traditional SSM algorithm is an efficient algorithm for the parameter estimation of nonlinear system of 1-D.The parameters estimation of nonlinear system of 2-D through some state space matrixes is presented in this paper,which can produce a new way for pairing the frequencies.The simulation results indicate that the algorithm has the features of strong noise suppression,low computational complexity,high resolution and small variance. |
