一种基于采样系统性质分析的连续系统传函辨识新方法

A NEW METHOD FOR THE IDENTIFICATION OF CONTINUOUS SYSTEMS BASED ON THE ANALYSIS OF THE PROPERTY OF SAMPLED SYSTEM

本文研究了任一连续系统采样后的性质,提出了一种无需时频转换(FFT运算)而直接求取连续系统传函模型的辨识新方法.它适用于在线或离线递推,计算简便、精确性好,且很容易推广到多输入多输出模型的辨识.

The property of a general continuous sampled system is analysed, and a new direct method for continuous transfer function identification without FFT is proposed. The algorithm is simple, rapid, and accurate, and can be realized on-line or off-line. Also it is straight to extend this method to MIMO system identification.
