复合组件

通过连接多个组件来构造自定义组件

复合组件由多个其他组件构造而成。要创建复合组件，您必须列出成员（构成）组件的名称，然后指定成员组件的端口如何相互连接以及如何连接到复合组件的外部端口。您还可以在复合组件的模块对话框中指定成员组件的哪些参数可见可调。

语言语法

`components`	Declare member components included in composite component
`connect`	Connect two or more component ports of the same type
`connections`	Define connections for member component ports in composite component
`import`	Import model classes

subsystem2ssc Convert subsystem containing Simscape blocks into equivalent Simscape file or files

About Composite Components
A composite component is constructed out of other components.
Declaring Member Components
A components declaration block begins with a components keyword and is terminated by an end keyword.
Parameterizing Composite Components
Composite component parameters let you adjust the desired parameters of the underlying member components from the top-level block dialog box when building and simulating a model.
Specifying Initial Target Values for Member Variables
Member components have to be declared with ExternalAccess=observe, and therefore their variables do not appear in the Variables tab of the top-level block dialog box.
Specifying Component Connections
The structure section of a Simscape™ file is executed once during compilation.
Composite Component — DC Motor
This example shows how to implement a DC motor model by means of a composite component.
Importing Domain and Component Classes
An import mechanism provides a convenient means to accessing classes defined in different scopes, or namespaces.
Composite Component Using import Statements
This example shows how you can use import statements to implement a DC motor model by means of a composite component.
Converting Subsystems into Composite Components
You can generate a composite component from a subsystem consisting entirely of Simscape blocks.

Defining Component Variants
Use conditional sections to define variants within component file.
Component Variants — Series RLC Branch
This example shows how to implement variants within a component file by using conditional sections.

Component Arrays
Use parametric-sized arrays of member components in composite components.
Segmented Pipeline Using Component Array
This example shows how you can model a segmented pipeline using an array of identical pipe segments, connected in series. The size of the array corresponds to the number of segments, and the block user can modify this parameter.
Segmented Pipeline with Different Pipe Lengths Using Component Array
This example shows how you can model a segmented pipeline with segments of different lengths, connected in series, using an array of components. The block user provides the lengths of individual pipe segments, and the model automatically determines the size of the array based on that data.
Case Study — Battery Pack with Fault Using Arrays
This case study shows how you can use component arrays to model a battery pack consisting of multiple series-connected cells. It also shows how you can introduce a fault into one of the cells to see the impact on battery performance and cell temperatures. The block user can modify both the number of cells and the position of the faulted cell as block parameters.
Arrays of Nodes
Use parametric-sized arrays of nodes to specify element-wise connections between arrays of components.
Using MATLAB Functions with Arrays of Components and Nodes
Use array manipulation and query functions on an object array.
