合成信号

使用合成信号（例如总线）对信号进行分组并降低模型的复杂度

为了简化模型外观，可以使用以下方法将各信号组合为合成信号：

有关合成信号的详细比较，请参阅合成信号的类型。

使用虚拟总线可满足建模时将信号合并为合成信号的大部分要求，并可灵活地合并不同类型的信号。

模块

Bus Assignment	为指定的总线元素赋予新值
Bus Creator	根据输入元素创建总线
Bus Selector	从传入总线中选择元素
In Bus Element	Select input from external port
Out Bus Element	Specify output that connects to external port

Demux	提取并输出虚拟向量信号的元素
Mux	将相同数据类型和复/实性的输入信号合并为虚拟向量
Selector	从向量、矩阵或多维信号中选择输入元素
Vector Concatenate, Matrix Concatenate	串联相同数据类型的输入信号以生成连续输出信号

Bus to Vector	将虚拟总线转换为向量
Signal Conversion	将信号转换为新类型，而不改变信号值

`Simulink.Bus`	指定总线的属性
`Simulink.BusElement`	指定总线元素的属性
`Simulink.Bus.cellToObject`	Convert cell array containing bus information to Simulink.Bus objects
`Simulink.Bus.createObject`	从模块或 MATLAB 结构体创建 `Simulink.Bus` 对象
`Simulink.Bus.objectToCell`	Use Simulink.Bus objects to create cell array containing bus information
`Simulink.Bus.save`	Save Simulink.Bus objects in function

Simulink.Bus.createMATLABStruct 创建与总线使用相同的层次结构和属性的 MATLAB 结构体

Simulink.BlockDiagram.addBusToVector Convert virtual bus signals into vector signals by adding Bus to Vector blocks

总线编辑器	创建、修改和管理总线对象
模型资源管理器	View, modify, and add elements of Simulink models, Stateflow charts, and workspace variables
