摘要
对非线性连续一离散系统的极大似然参数估计方法导出了一种速推计算灵敏度的新算式.该算式借助二水平正交表的性质,避免了原灵敏度递推算式中的矩阵求道运算.仿真实例验证了该算法的实用性和有效性.
A set of new formulas of recursive computing sensitivities is developed for maximum likelihood estimation method to the nonlinear continuous-discrete systems.The inverse operation of matrix in the algorithm of recursive computing sensitivities is avoided by the properties of orthogonal table with two sample points. The simulation example. shows the effectiveness and practicality of the proposed formulas.
