Simulink Fault Controls

Use Simulink functions to model faults

You can use these Simulink fault controls in Simscape models to analyze, configure, and remove faults, behaviors, triggers, and conditionals.

Topics

Create and Manage Conditionals
Use conditionals to define conditions that you can use to trigger faults.
