Information

The FaultTriggering Toolbox accomodates 2 fault types;

1. Parameter Faults: Faults that at set at the beginning of each simulation.
2. Variable Faults: Faults that can vary during simulation time.

Both Faults can be several data types:

1. Boolean: Triggering a hard fault like Actuator disconnects, Rollerscrew jam and the Breakage of electrical cable.
2. Integer: Can trigger fault cases like Sensor faults (sensor has a zero output, sensor saturates, ...)
3. Real: Can be used to set fault levels like bearing friction, increasing pressure losses.

All Fault models are supplied in FaultTriggering.FaultOutput.

All Variable Faults are controlled by a global model "broadcasting" the faults. Each variable fault therefore must be coupled to a fault channel from the global FaultTriggering model. This makes also external triggering of the faults (e.g. from Simulink) possible.

Using these fault models all commonly know faults can be modelled. In Fault Modelling is explained how to use these blocks.
