摘要: 受控自回归自回归模型也称为方程误差自回归模型。利用采集的批量数据和迭代搜索, 论文基于滤波辨识理念, 研究和提出了方程误差自回归系统的滤波广义梯度迭代辨识方法、滤波多新息广义梯度迭代辨识方法、滤波广义最小二乘迭代辨识方法、滤波多新息广义最小二乘迭代辨识方法。这些滤波广义迭代辨识方法可以推广到其它有色噪声干扰下的线性和非线性多变量随机系统中。

Abstract: The controlled autoregressive autoregressive model is also called as the equation-error autoregressive model. By using the collected batch data and the iterative search, and based on the filtering identification idea, the paper studies and proposes the filtered generalized gradient-based iterative identification method, the filtered multi-innovation generalized gradient-based iterative identification method, the filtered generalized least squares-based iterative identification method, and filtered multi-innovation generalized least squares-based iterative identification method for equation-error autoregressive systems described by the equation-error autoregressive models. These filtered generalized iterative identification methods can be extended to other linear and nonlinear multivariable stochastic systems with colored noises.

 

Key words: parameter estimation; iterative identification; multi-innovation identification; hierarchical identification; least squares; gradient search; stochastic system
