  1. Two - stage algorithms of parameter estimation for the autoregressive moving average ( arma ) models are presented, which are called two - stage recursive least squares algorithm ( 2 - rls ) and recursive least squares - pseudoinverse algorithm ( rls - pi )

    本文提出了自回歸滑動平均（ arma ）模型的兩段參數估計演算法：兩段遞推最小二乘演算法（ 2 - rls ）和遞推最小二乘-偽逆演算法（ rls - pi ） 。
  2. Compared with classical recursive extended least squares, their accuracy obviously is improved. applying these new algorithms to the parameter estimation problem for systems with measurement noises, some new approaches and algorithms of parameter estimation for system with measurement noises, are presented, for example, two - stage rels - gevers - wouters algorithm and three - stage rls - pi - gevers - wouters algorithm, which solve the biased parameter estimation problem by classical least squares method

    並將這些演算法推廣到帶觀測噪聲系統參數估計的問題，給出了帶觀測噪聲系統參數估計的一些新方法和新演算法，其中包括兩段rels - gevers - wouters演算法和三段rls - pi - gevers - wouters演算法，解決了用普通最小二乘法估計帶觀測噪聲系統未知參數的有偏問題。
  3. Based on the classical least squares method ( rls ) in system identification, the several new identification algorithms of parameter estimation for the autoregressive moving average ( arma ) model, are presented. they include univariable and multivariable two - stage recursive least squares - recursive extended least squares ( rls - rels ) and two - stage recursive least squares - pseudo - inverse ( rls - pi ) algorithms

    本文在系統辨識經典的最小二乘法（ rls ）的基礎上，提出了自回歸滑動平均（ arma ）模型參數估計的一些新的辨識演算法，它包括單變量和多變量兩段遞推最小二乘?遞推增廣最小二乘（ rls ? rels ）演算法和兩段遞推最小二乘?偽逆（ rls ? pi ）演算法等。
