Review the Control Algorithm of Rotator in Phase 2

    XMLWordPrintable

    Details

      Description

      This task will review the rotator Simulink model and try to reproduce the error we had on the summit test that the demand rotator position can be -2000 peak. Another error we have is the peak between tracking targets. We will also investigate the stop profile in model. This is the phase 2 of DM-24799.

            Track a target at 3 deg, stop at time=2.2 second, put the system into the SlewAndTrack model again at time=7.1 second. In the mean time, at time=7 seconds, track another target at -1.5 deg. We saw the system was put into the controlledStopping mode by itself at time=8.2 seconds. The system entered the Fault state at a latter time and the Simulink crashed:

            Updated the interface to give the track commands in rotator Simulink model.

            Reviewed PR in github. I think we could consider turning these note in the Jira ticket into a tech note, this would also help us figuring out what to do to solve these issues. Maybe instead of going straight to implementing changes in the Simulink model you could spend 1 or 2 story points writing a tech note with the findings in here and proposed solution.
