一种用于参数估计的几何距离最小二乘方法

A Geometric Distance Least Square Method Used for Parameter Estimation

本文从解析几何中几何距离角度出发,对系统辨识或参数估计提出一种全新的几何距离最小二乘方法。理论分析和应用实例表明,几何距离最小二乘方法同样也是一种比较有效的参数估计方法。

Based on the definition of geometric distance in analytical geometry, this paper proposes a new geometric distance least square method used for parameter estimation or system identification. Theoretical analyses and applications all show that the geometric distance least square method is also a good and effective parameter estimation method.
