Dynamic Response Curve Fitting Technology for Linear System Based on MATLAB

本文以高阶线性时不变系统为研究对象,选定系统结构和参数,通过传递函数中参数和曲线形状的关系来调节参数,以达到获得预定曲线形状的目的。本文的目的是采用MATLAB GUI编制并实现一个用于线性系统动态响应曲线拟合的程序,通过手动调节系统参数来拟合响应曲线,同时显示各子系统的响应曲线和总的误差曲线。

In this paper,the high-order linear time-invariant system is taken as the research object,the system structure and parameters are selected,and the parameters are adjusted by the relationship between the parameters and the curve shape in the transfer function,so as to achieve the purpose of obtaining the predetermined curve shape.The purpose of this paper is to compile and implement a program for dynamic response curve fitting of linear system by using MATLAB GUI,to fit the response curve by manually adjusting the system parameters,and to display the response curves of each subsystem and the total error curves.
