.FaultTriggering.UsersGuide.Overview

Information

In this package, models are supplied to trigger faults in an consistent way. Several types of faults are included:

• Parameter Faults (Real,Integer as well as Boolean). These can be set at the beginning of each simulation run.
• Variable Faults (Real,Integer as well as Boolean). Can be changed during simulation time.

These blocks can be simply added as sources. The blocks have default values which can be used for testing or the case where the faults are not interesting.

An example model with integrated faults can look like this:

It is possible to identify the sources of the faults. Moreover it is possible to generate text-only models using internal fault sources.

An algorithm with searches the complete model on models which use a certain model type. The result of this seach is used to create a wrapper library where the user can specify the fault parameters in a central block.

Such a wrapper model can look like:

The faults can be set using the faultTrigger instance. Inside this model, the fault can be set as shown in the following figure:

The parameter faults can be set directly in the model by ajusting the parameters of the fault block.
