摘要
本文基于系统辨识的最小二乘法,介绍一种用Basic语言编程的SISO线性系统系统辨识软件包及其原理、结构、功能与特点。它包括输入/输出数据的生成,近十种辨识程序模块的调用,结果的处理,模型阶次与纯滞后时间的确定和模型校验等五大部分。经应用已证明设计合理,方便可靠,并具有结构简单灵活等特点。
Based on the Least Squares Method, this paper introduces a sort of System Identification software package for SISO system in Basic Language as well as its principles, components, functions and characteristics. It involves five parts of Input-output data generation, program block call of about ten sorts, result treatment, model order and delay time determination and model verification.The application of this software package shows that it possesses features of reasonable design, convenience in use, reliability, simple structure and flexibility.
