Units in Simulink
Simulink enables you to specify physical units as attributes on signals at the boundaries of model components. By specifying, controlling, and visualizing signal units, you can ensure the consistency of calculations across the various components of your model. For example, this added degree of consistency checking might be useful if you are integrating many separately developed components into a large, overall system model. To get started with units, see Unit Specification in Simulink Models.
|Inport||Create input port for subsystem or external input|
|Outport||Create output port for subsystem or external output|
|Signal Specification||Specify desired dimensions, sample time, data type, numeric type, and other attributes of signal|
|Unit System Configuration||Restrict units to specified allowed unit systems|
|Unit Conversion||Convert units|
- Unit Specification in Simulink Models
Specify physical units as attributes on signals at the boundaries of model components.
- Displaying Units
Dynamically update port and signal labels to show any changes made to units.
- Update an Existing Model to Use Units
Use a fuel control system example to learn how to update an existing model to use units.
- Unit Consistency Checking and Propagation
Check unit consistency between components.
- Converting Units
Configure Simulink to convert units between ports when discrepancies that have known mathematical relationships are detected.
- Working with Custom Unit Databases
Create and load custom unit databases from Excel® spreadsheets.
Use Model Advisor checks to troubleshoot common issues with unit settings.
