基于MATLABGUI平台的用于控制系统计算机辅助分析与设计的软件的设计与实现计算机毕业设计学位论文范文模板参考资料.doc

大庆石油学院本科生毕业设计（论文） PAGE III 摘 要 MATLAB语言是一种十分有效的工具，能容易地解决在系统仿真及控制系统计算机辅助设计领域的教学与研究中遇到的问题，它可以将使用者从繁琐的底层编程中解放出来，把有限的宝贵时间更多地花在解决科学问题上。MATLAB GUI是MATLAB的人机交互界面。由于GUI本身提供了windows基本控件的支持，并且具有良好的事件驱动机制，同时提供了MATLAB数学库的接口，所以GUI对于控制系统仿真的平台设计显得十分合适。GUI对于每个用户窗口生成.fig和.m文件。前者负责界面的设计信息，后者负责后台代码的设计。 本文所做的研究主要是基于MATLAB GUI平台，结合控制系统基础理论和MATLAB控制系统工具箱，实现了用于控制系统计算机辅助分析与设计的软件。本软件主要功能：实现传递函数模型输入、状态方程模型输入、模型装换、控制系统稳定性分析、系统可观性可控性判断，绘制系统奈奎斯特图、波特图、根轨迹图以及零极点分布图。在继续完善的基础上能够用于本科自动控制原理教程的教学实验和一般的科学研究。 关键词：控制系统；MATLAB GUI；计算机辅助设计 Abstract MATLAB language is a very effective tool,and can be easily resolved in the system simulation and control system of teaching in the field of computer-aided design and research problems,it could be the bottom of the user from tedious programming liberate the limited spend more valuable time to solve scientific problems.The MATLAB GUI is the interactive interface.As the GUI itself provides the basic control windows support,and has a good mechanism for event-driven,while providing the MATLAB Math Library interface，the GUI for control system simulation platform for the design of it is suitable. GUI window generated for each user. Fig and.M file. The former is responsible for the design of the interface information,which is responsible for the design of the background code. Research done in this article is mainly based on MATLAB GUI platform,the basis of combination of control system theory and MATLAB Control System Toolbox,the realization of control systems for computer-aided analysis and design software. The main functions of the software: the realization of transfer function model input,the state equation model input,the model fitted for the control system stability analysis,system observability controllability judgments、rendering the system Nyquist diagram、Bode plots、root locus and Pole-zero distribution. While continuing to improve based on the principle of automatic control can be used for undergraduate teaching course experiments and scientific research in g
