空燃比控制系统与Stateflow图表
生成代码的空燃比控制系统设计与仿真软件®和Stateflow®。金宝app
图1、2和3显示sldemo_fuelsys模型的相关部分,包含植物和控制器的闭环系统。工厂验证控制器在设计周期的早期在模拟。在本例中,您生成代码相关控制器子系统,“fuel_rate_control”。图1显示了高层仿真模型。
开放和配置sldemo_fuelsys模型。然后,编译模型信号数据类型。

配置和构建模型与嵌入式编码器
配置和构建生产ANSI®C / c++代码模型,设定模型配置参数系统目标文件来ert.tlc(嵌入式实时(ERT))。你可以设置系统目标文件参数编程。
rtwconfiguredemo (“sldemo_fuelsys”,“导”);
生成和检查代码。你可以导航到相关代码段交互使用以前的和下一个按钮。从图表上下文菜单(右键单击Stateflow块),选择C / c++代码>导航到C / c++代码。通过编程,使用rtwtrace实用程序。
