MATLAB环境下的系统辨识仿真工具箱

介绍了在MATLAB环境下构建一种新的系统辨识仿真工具箱(SIST:SystemIdentificationToolbox)的原理与实现,讨论了在MATLAB环境下工具箱的数据和算法结构形式,以及利用GUIDE完成图形界面的设计,用MATLAB与C 混编技术实现物理系统的I/O接口和系统辨识模型与算法、报告文件(report)和帮助文档等功能模块的编程。这种在MATLAB环境下开发的系统辨识仿真工具箱,具有功能丰富、可扩展性好、使用方便、操作直观等特点。还给出了实际使用例,证实工具箱的有效和可靠,可作为辨识研究和教学的辅助工具。

System Identification and Simulation Toolbox under MATLAB Environment

A new construction of System Identification and Simulation Toolbox(SIST)was introduced under MATLAB environment by discussing about its principle and realization.The structure of data and algorithms,the design of graphic interface using GUIDE,and the physical system I/O interface with MATLAB/C hybrid programming were shown.Also,the programming of the model-types and recursive algorithms,the report file and the help documents etc were reffered.The toolbox built under MATLAB environment has many advantages,such as its powerful functions,good expandability,convenient usage,direct interaction and so on.An example was given at the end to use the toolbox on a real system,which shows its reliability and usefulness,and confirms that the toolbox is a good tool for the research and study on identification.
