Open and Explore Model

In this example, we use the model of a mass springer damper system. The mass-spring-damper model consists of discrete mass nodes distributed throughout an object and interconnected via a network of springs and dampers. This model is well-suited for modelling object with complex material properties such as non-linearity and elasticity. In this example we use the mass spring damper system. The system is parametrized by mass (m), spring stiffness (k), damping (b) and the initial position (x0). The input to the system is the applied force.

要探索具有可调参数的不同值的不同值的模型，请创建以下模型工作区变量：

To create the model workspace variables, go to the造型tab and select模型工作区在里面Data Repositories在里面Designsection. Use theAdd MATLAB Variablesicon to add the above four variables. Add the appropriate initial values, for example, 3, 128, 2 and 0.5 respectively.

在应用程序设计器中创建应用程序

使用MATLAB应用程序设计器创建一个应用程序，以模拟具有不同参数值和输入信号的模型。要了解有关如何使用应用程序设计师创建应用程序的更多信息，请参见Create and Run a Simple App Using App Designer使用massspringdamperapp.mlappfile to use the app.

MassSpringDamperapp

应用详细信息

应用程序的主要部分是模拟按钮回调函数。它具有以下明显部分：设置仿真input目的，configure it for deployment, simulate, and plot the simulation results.

The functionality of the application to change and experiment with the tunable parameters is defined in the callback function模拟ButtonPushed。此回调功能使您可以通过修改应用程序设计器中的值来更改，实验和分析不同的模拟。

模拟Buttonpushed回调功能代码

This section explains the code written to create the app,MassSpringDamperapp。The callback function模拟ButtonPushedis called in the app designed in the App Designer. This callback function defines how the model is simulated. We use theSimulink.SimulationInput对象将变量设置为模型并使用这些变量来更改值并分析模型。

创建Simulink.SimulationInputObject in the模拟ButtonPushed功能

在里面模拟ButtonPushed功能，创建一个仿真input目的，SimInp for the modelMassSpringDamperModel。使用setModelParametersmethod on the仿真inputobject. In this example, we set theStopTimemodel parameter for the simulation.

Set the Values of the Tunable Parameters and the Input Signal

要将输入信号设置为模型，请使用ExternalInput属性Simulink.SimulationInput目的，siminp。使用setVariablesmethod to set the values of the four tunable parameters. Create the force input signal and set it as theExternalInput在仿真输入对象中。

配置用于部署

Now that we have assigned all the values to the variables and set the input signal, theSimulink.SimulationInput需要配置对象进行部署。使用SIMulink.compiler.configureForDeploymentfunction of Simulink Compiler. This function handles all the settings required for the script to be compatible for deployment by setting the simulation mode to rapid accelerator, and by setting the parameterRapidAcceleratorUpToDateCheckto离开。

模拟和绘制结果

使用configured Simulink.SimulationInput object to run the simulation with theSIM命令。使用仿真绘制结果Simulink.SimulationOutput目的，SIMOut。

Test Out the Application in App Designer

在部署应用程序之前，请确保应用程序在应用程序设计器中运行。点击模拟应用程序上的按钮可以通过模拟不同值的模型来验证应用程序是否有效。

编译脚本进行部署

要编译应用程序，请使用MCC命令，然后是脚本名称。

MCC -M MasspringDamperapp.mlapp
