利用相关分析法辨识系统脉冲响应

Identifying the Pulse Response of Control System with a Method of Correlative Analysis

在系统的设计过程中建模起着重要的作用，相关分析法是一种辨识系统脉冲响应的基本方法。为保证辨识精度，缩短程序运行时间，采用M序列作为输入信号，通过对一个二阶系统的脉冲响应辨识，效果良好。

During the process of system designing, it is important that the model of system is built up. The method of correlative analysis is a basic way with which we can identify pulse response of control system. In order to ensure the precision of identified results and reduce the cycle of program running, M sequence is used as the input signal of system. The identifying result of actual system shows that the method of correlative analysis is better.
