基于LabVIEW的SIP系统辨识设计与实现

Design and Implementation of Identification for SIP System Based on LabVIEW

系统辨识是得到系统模型的一种重要途径,在现代控制工程中,利用系统的输入与输出对系统进行相关辨识,是近年来迅速发展起来的新技术。本文以大亚湾核电站SIP系统的一些动态模块为例,通过数据采集卡及LabVIEW开发环境实现对动态模块的信号注入、信号采集、数据处理等功能,利用LabVIEW的系统辨识工具包可以快速方便的完成系统辨识功能。

the system identification is the important method to get the model of system, in the modem control project, using the input and output of system to make the identification is the rapid development of the new technology. This article in the background of some dynamic model of SIP system in the nuclear power station, realize the function of the data input, data sampling ,and data processing for dynamic model by the data acquire device and LabVIEW environment. Using the system identification tools can easily to complete the function of system identification.
