If the rotator does not receive the track command for a long time, the rotator should be put into the Fault state. This could be 0.5 second (by Tiago) or 1 second (by Russell). At this moment, we do see this in the Simulink model by the simulation experiment, but we do not know how that is decided. In addition, we did not see this when we did the test on summit. This task needs to figure out what is the existed logic in model and how to update it.
The following is the figure to show the simulation result (detail is at
The system is at the Fault state around time equals 20.2 seconds (no new track command after time=6 seconds).
