Support the rotator test on summit. This is to collect the data of controller parameters.
Check there is the “forced oscillation” in the rotator or not. If it is, the oscillation frequency will change with speed. Therefore, measure the oscillation frequency at each speed and check if it is related to something, for example:
1. Rotation speed of the motor, of the pinion or of the crown
2. Rotation speed of the pinion or crown multiplied by their number of teeth…
If it is, we should review mechanically the source of the oscillation because the controller is simply reacting to that oscillation (trying to eliminate it).
Need to analyze the data: analysis_fail
This is the binary file that I recorded the condition that the rotator can not do the tracking at the second time of test.
Please review the PR:
I noticed that I have the data of MOOG's tracking result at 3/28:
The result is:
Check the checking target from 0.7 degree to 1.5 degree with the velocity of 0.068 degree/second:
The maximum of position error is 13.388 arcsec and the RMS is 3.783 arcsec.
Under the same condition, the Tekniker controller can reach the results that the maximum of position error is 0.787 arcsec and the RMS is 0.258 arcsec already.
