matlab 变压器 软件开发

在 MATLAB 中开发变压器选型软件，可以采用 GUI（图形用户界面）设计方式，方便用户进行输入和操作。以下是一个简单的变压器选型软件开发流程：

1. 确定软件功能：根据用户需求，确定软件的功能，例如变压器选型、成本计算、结果输出等。

2. 设计 GUI 界面：使用 MATLAB 的 GUIDE 工具箱，设计软件的图形用户界面，包括输入框、按钮、下拉菜单等控件。

3. 编写逻辑代码：根据软件的功能需求，编写 MATLAB 代码实现变压器选型、成本计算等功能。

4. 集成 GUI 界面和逻辑代码：将 GUI 界面和逻辑代码集成起来，实现用户输入和操作与数据处理的连接。

5. 测试和优化：对软件进行测试，发现问题并进行优化，确保软件的稳定性和可靠性。

下面是一个简单的变压器选型软件开发示例，包括 GUI 界面设计和逻辑代码实现：

1. GUI 界面设计：

使用 GUIDE 工具箱设计一个包含输入框、下拉菜单和按钮的图形用户界面，如下图所示：


2. 逻辑代码实现：

在 MATLAB 中编写逻辑代码实现变压器选型和成本计算功能，并将其与 GUI 界面集成。

下面是一个简单的示例代码，用于实现变压器选型和成本计算功能：

function varargout = transformer_gui(varargin)
% TRANSFORMER_GUI MATLAB code for transformer_gui.fig
%      TRANSFORMER_GUI, by itself, creates a new TRANSFORMER_GUI or raises the existing
%      singleton*.
%
%      H = TRANSFORMER_GUI returns the handle to a new TRANSFORMER_GUI or the handle to
%      the existing singleton*.
%
%      TRANSFORMER_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TRANSFORMER_GUI.M with the given input arguments.
%
%      TRANSFORMER_GUI('Property','Value',...) creates a new TRANSFORMER_GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before transformer_gui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to transformer_gui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @transformer_gui_OpeningFcn, ...
                   'gui_OutputFcn',  @transformer_gui_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end
% End initialization code - DO NOT EDIT


% --- Executes just before transformer_gui is made visible.
function transformer_gui_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to transformer_gui (see VARARGIN)

% Choose default command line output for transformer_gui
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes transformer_gui wait for user response (see UIRESUME)
% uiwait(handles.figure1);

% 设置下拉菜单选项
set(handles.popupmenu1, 'String', {'型号1', '型号2', '型号3'});
set(handles.popupmenu1, 'Value', 1);

% --- Outputs from this function are returned to the command line.
function varargout = transformer_gui_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure
varargout{1} = handles.output;


% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% 读取输入框和下拉菜单的值
n = str2double(get(handles.edit1, 'String'));
m = get(handles.popupmenu1, 'Value');

% 计算成本
c = [100, 200, 300];
x = zeros(1, 3);
x(m) = n;
cost = x * c';

% 显示结果
set(handles.text3, 'String', num2str(cost));

上述代码中，通过设置下拉菜单的选项和按钮的回调函数，实现了用户输入和操作与数据处理的连接。逻辑代码部分计算了变压器选型的成本，并将结果显示在 GUI 界面上。
