Composite Components

Construct custom components by connecting multiple components

A composite component is constructed out of other components. To create a composite component, you have to list the names of the member (constituent) components and then specify how the ports of the member components are connected to each other and to the external ports of the composite component. You also specify which parameters of the member components are to be visible, and therefore adjustable, in the block dialog box of the composite component.

Basic Techniques for Creating Composite Components

Component Variants

Component Arrays

  • 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.
