摘要
论文介绍了用LabVIEW软件设计一种新的辨识仿真实验平台的原理、方法及其结构和功能特点。文中所开发的实验平台是集软件、硬件一体,能实现实时采样、数据处理、辨识、仿真等功能的实验系统。LabVIEW是开发虚拟仪器的一个常用软件。通过LabVIEW设计了程序的主要逻辑流程、与实际系统的硬件I/O接口和辨识仿真平台的用户界面;利用MATLAB语言设计辨识、仿真算法;并设计了远程访问等功能。利用该平台所作实验、仿真和分析结果证明了该平台是进行辨识实验研究的一种实用有效的工具,可供给工程研究和教学实验之用。
This article introduces the principle and method of a new design of the experimental platform for identification and simulation, as well as the features of its structure and functions. This platform is a system that integrates both hardware and software. It has the ability for data sampling, data - preprocessing, identification and model simulation etc. The LabVIEW software is a popular tool for developing virtual instruments, with which the main logical structure of the program, the I/O port for hardware and the human machine interface were designed. The identification algorithms and simulation methods were written by MATLAB language. And some other functions such as remote access were also been developed. Experiments and simulations were done by this platform; the analysis results proved that this platform is an efficient tool to help the researches on the system identification and education.
