基于MATLAB电路特性演示平台的设计毕业设计论文

洛阳理工学院毕业设计（论文）I基于MATLAB电路特性演示平台的设计摘要电路特性是用复杂的数学公式描述的，非常抽象，难以理解。MATLAB具有强大数学计算和图形显示功能，它可以方便的计算出非常抽象、复杂的数学公式。此外，它提供了图形用户界面设计工具GUIDE，其包含的各种控件，易于开发，交互性强、使用方便。本论文基于MATLABGUI开发设计的电路特性演示平台。平台共包含有8个常见的、典型电路的特性演示和方波傅里叶分析。各演示平台的开发是在已建立的数学模型的基础进行的，利用MATLAB中的GUIDE设计工具完成了用户界面的设计，界面中各种控件的功能是通过编写其回调函数来实现的。在演示过程中，通过调整相关的参数，动态演示电路参数变化时电路特性的变化情况。该系统平台具有良好的用户界面、交互性强、操作方便，可以使用户直观、高效地观察和理解电路的特性。关键词：MATLAB，数学模型，电路特性，演示平台,GUIDE洛阳理工学院毕业设计（论文）IITheDesignoftheCircuitcharacteristicsofMATLAB-basedpresentationplatformABSTRACTCircuitperformanceistousecomplexmathematicalformulasdescribed,veryabstractanddifficulttounderstand.MATLABhasapowerfulmathematicalandgraphicaldisplay,itcaneasilycalculatetheveryabstractandcomplexmathematicalformula.Inaddition,itprovidesagraphicaluserinterfacedesigntoolGUIDE,whichcontainsthevariouscontrols,easy-to-development,interactive,easytouse.Thispaper,basedonMATLABGUIdevelopmentanddesignofthecircuitfeaturesdemoplatform.Platformcontainsatotalof8common,thecharacteristicsofatypicalcircuit,andsquarewaveFourieranalysisshows.Thedemonstrationplatformwasdevelopedtobuildonthebasisofmathematicalmodels,theuseofMATLABintheGUIDEuserinterfacedesigntoolstocompletethedesignoftheinterfacefunctionsofthevariouscontrolsisthroughthepreparationofthecallbackfunctiontoachieve.Inthedemo,byadjustingtherelatedparameters,dynamicparametersdemonstratesthecircuitcharacteristicsofcircuitchanges.Theplatformhasagooduserinterface,interactive,easytooperateandallowsuserstodirectlyandefficientlyobserveandunderstandthecharacteristicsofthecircuit.KEYWORDS:MATLAB，Mathematicalmodel，Circuitcharacteristics，Demonstrationplatforms，GUIDE洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章MATLAB简介......................................................................21.1MATLAB简介.......................................................................21.1.1MATLAB概述.............................................................21.1.2图形界面（GUI）概述...............................................2第2章电路数学模型的建立...........................................................42.1RC积分和微分电路..............................................................42.2谐振电路的频率特性...........................................................42.3方波的傅里叶分析...............................................................52.4二阶电路零输入响应...........................................................52.5正弦激励的一阶电路...........................................................62.6低通滤波电路.......................................................................72.7高通滤波电路.......................................................................82.8带通滤波电路.......................................................................82.9带阻滤波电路.......................................................................9第3章系统结构设计.....................................................................103.1系统设计思想.....................................................................103.2系统层次结构.....................................................................10第4章GUI设计.............................................................................124.1界面设计编辑器.................................................................124.2GUI主要控件对象及属性介绍...........................................134.2.1控件的常用公共属性...............................................134.2.2命令按钮（PushButton）控件................................144.2.3静态文本框（StaticText）控件...............................144.2.4可编辑文本框（EditText）控件.............................144.2.5滑动条（Slider）控件..............................................144.2.6坐标轴（axes）控件................................................154.2.7组面板（Uipanel）控件...........................................15洛阳理工学院毕业设计（论文）IV第5章界面及程序代码.................................................................165.1主界面设计.........................................................................165.1.1界面设计...................................................................165.1.2控件回调函数编写...................................................175.2RC积分和微分电路界面设计.........................................175.2.1界面设计...................................................................185.2.2控件回调函数编写...................................................195.3谐振电路频率特性.............................................................205.3.1界面设计...................................................................205.3.2控件回调函数编写...................................................215.4方波的傅里叶分析.............................................................225.4.1界面设计...................................................................225.4.2控件回调函数编写...................................................225.5二阶电路的零输入响应.....................................................235.5.1界面设计...................................................................235.5.2控件回调函数编写...................................................245.6正弦激励的一阶电路.........................................................255.6.1界面设计..........................................................
