New AA filter make INPUT yaw oscillation disappear

After the discussion with Eleonora and Matteo, I modified the filters for AA. For old and new filters, the comparison of AA diagonalized signal is shown in the attached figure. (Blue is the old case, red is the new case)

The new filter configuration is as following:

 

gain

poles

zeros

INPUT_Y

10

0,30

1.5

INPUT_P

8

0,30

2

END_P

10

0,30

2

END_Y

12

0,30
