摘要: 利用递阶辨识原理,研究和提出了方程误差自回归滑动平均(EEARMA)系统的递阶广义增广梯度迭代辨识方法、递阶广义增广最小二乘迭代辨识方法、递阶多新息广义增广梯度迭代辨识方法、递阶多新息广义增广最小二乘迭代辨识方法。这些递阶广义增广辨识方法可以推广到其他有色噪声干扰下的线性多变量和非线性多变量随机系统中。

Abstract: By using the hierarchical identification principle, this paper presents a hierarchical generalized extended gradientbased iterative identification method, a hierarchical generalized extended least squaresbased iterative identification method, a hierarchical multiinnovation generalized extended gradientbased iterative identification method and a hierarchical multiinnovation generalized extended least squaresbased iterative identification method for equationerror autoregressive moving average systems. The proposed hierarchical generalized extended iterative identification methods can be extended to other linear and nonlinear multivariable stochastic systems with colored noises.
Key words: parameter estimation; iterative identification; multiinnovation identification; hierarchical identification; least squares; stochastic system
