| Failure Mode | Detection | Isolation / Safe Mode | Recovery |
|---|---|---|---|
| Sensor bias / dropout | Redundancy, out-of-range checks, rate checks, residuals | Flag sensor invalidity, use backup, and reduce authoriuty | Sensor reset → offset compensation where valid |
| Unexpected torque | Model vs measured residuals | Switch to damping mode, inhibit impulses | Let residuals decay and re-estimate states |
| Spin-axis misalignment | Orientation vs expected dynamics | Reduce authority, re-acquisition | Re-estimate axis and update control parameters |
| Partial power loss | Voltage / Current thresholds | Disable non-essential processes and maintain survival | Gradually restore functions as power stabilizes |
FDIR = Continuously:
Observe system state
Compare to model/expectations
Flag anomalies
Enter a safe mode
Attempt recovery
Only return to nominal when consistent
