高阶矩法辨识非最小相位系统

Identification of Non-Minimum Phase Systems by Cumulants

本文对八十年代发展起来的高阶矩方法作了分析和综述，将其应用于输出已知条件下的系统辨识问题中．借助高阶矩方法，可以准确有效地辨识系统的相位，从而克服了传统方法的弱点．

In this paper, we analyse and review the cumulant methods, which are developed in recent years, and apply it to the system identification problems with noly output known. By means of higher-order cumulants, we can resolve the phase problem, which is a main drawback of all the traditional methods in the area.
