Fault Detection, Isolation, and Recovery

Design algorithms to identify and manage system failures

Enable your safety-critical model to recover from system failures by using redundant logic and explicit transitions for every state. When system faults occur, detect and isolate them by using operating points. Test your model at specific fail times without rerunning the entire simulation.
